Celebrities say and do plenty of ridiculous things, but you've got to do something extraordinarily bad to make it into the worst WTF moments of 2012 category.

Whether it's proudly spewing racist or sexist comments, engaging in behavior that would get most people fired in two seconds, or just displaying a total lack of shame, some celebrities behaved in ways that have us giving them some serious side eye. And since most don't seem to have learned from the experience, let us do the facepalm for them.

Check out our roundup of the 15 biggest celebrity facepalm moments of 2012!

1. Adam Carolla Says "Dudes Are Funnier Than Chicks"

Between Tina Fey, Amy Poehler, and a slew of other successful female comedians, there's never been a better time to be a woman in comedy. Unless you're Adam Carolla and believe that woman are only hired as staff writers on shows to fill a quota. While promoting his latest book, Adam declared that "dudes are funnier than chicks" and that women aren't funny in general. "When you're picking a basketball team, you'll take the brother over the guy with the yarmulke. Why? Because you're playing the odds," he said. When it comes to comedy, of course there's Sarah Silverman, Tina Fey, Kathy Griffin -- super-funny chicks. But if you're playing the odds? No."

2. Lisa Lampanelli Calls Fellow 'Celebrity Apprentice' Contestant a "S**c"

The self-proclaimed "Queen of Mean" has made a career off jokes that poke fun at racial stereotypes, but Lisa proved some of her comic bigotry might actually be genuine. While promoting her stint on Celebrity Apprentice during a radio interview, Lisa spoke about her feud with fellow contestant Dayana Mendoza and used a racial slur against Hispanics to describe her. "I actually would love to see Dayana giving birth. She's a s**c! She'll be knocked up before the end of the week," she said. Despite negative backlash, Lisa has refused to apologize for her comment.

3. Paris Hilton Tries to Do Something Besides Be a Silly Ho, Fails Miserably

Just because you hang out at clubs all the time doesn't mean you know how to DJ. Paris learned that lesson the hard way while making her turntable debut at a festival last June in Brazil. She spent more time blowing kisses to the crowd than spinning records and her stint was booed by fans and universally slammed by critics.

4. Here Comes Honey Boo Boo Gets Renewed For a Second Season

We're not sure what gets a bigger facepalm here: the Boo Boo clan itself, or the fact that the public ate up their antics so much that the show was renewed for a second season! What started out as a six-episode experiment ended up being a more watched program than the Republican National Convention, providing further proof that America is completely and utterly screwed.

5. Anne Hathaway Gets Out of a Car With No Panties

At this stage of the game, Anne is a seasoned pro. She knows fully well that if you get out of a car sans underwear, your goods will be exposed and photographers will take pictures of it. Unfortunately, that didn't seem to be much of a concern when she showed up at the premiere for Les Misérables earlier this week. 

6. The Octomom Strips Away Her Clothes (and Dignity)

Show of hands: anyone want to watch infamous mother of 14 Octomom, a.k.a. Nadya Suleman, masturbate on video? No? Well, she didn't care and did it anyway. The sick "self-pleasure" tape showed her doing the act on top of a pile of baby clothes and was panned by the general public and even the porn community, yet somehow still managed to get nominated for a handful of AVN awards (i.e., the Oscars of porn).

7. John Travolta Says He Can Cure Major Injuries With Scientology

If you have major long-term injuries stemming from a car crash, you should probably see a doctor -- or John. The actor claimed he healed the injuries of a car crash victim through Scientology "assists" that he had no problem performing in front of a stunned (and creeped out) crowd in China. "You could actually see him confronting the pain and after awhile he looked up at me and said, ‘I feel better,' so I said ‘Okay, end of assist.' He had gotten noticeably better and I was chomping at the bit for more," he said. Between this and the holiday video with Olivia Newton-John, we're gearing up for a full-on meltdown from this man in 2013.

8. Daniel Tosh's Tasteless Rape Joke

What's funnier than a joke about rape? Well, lots of things. But not if you're Daniel Tosh. The comic committed a cardinal sin by directing a rape joke at an audience member during one of his shows this past summer. "Wouldn't it be funny if that girl got raped by like, five guys right now? Like right now?" he said. He later offered a kinda-sorta apology on Twitter, but spent more time justifying the joke than actually apologizing.

9. Dane Cook's Tasteless 'Dark Knight' Shooting Joke

There was definitely something in the comic water this summer -- and it wasn't humor. Shortly after Daniel's tasteless rape joke, Dane made a joke about the tragic shooting last July at a Colorado screening of The Dark Knight Rises. He said the movie was so bad: "... if none of that would have happened, I'm pretty sure that somebody in that theater, about 25 minutes in, realizing it was a piece of crap, was probably like, ‘Ugh, f***ing shoot me.’” However, unlike Daniel, Dane later offered a genuine apology on Twitter for his joke.

10. Courtney Stodden: "Sometimes I Call My Husband 'Dad'"

Let's be honest, Courtney's entire existence is pretty much one big facepalm. But the child bride and wannabe Paris Hilton took her relationship with 52-year-old Green Mile actor Doug Hutchison to a whole new level of creepiness by admitting that she sometimes confused him for her father. "I accidentally call him 'dad' — you know, Doug-dad, same thing," she said. In response, Doug admitted to often joking that he is "raising his wife." Yep, that relationship sounds real healthy.

11. Snoop Dogg Becomes Snoop Lion

We'd normally ask if someone was high when they made this type of decision, but it's a rhetorical question in the case of Snoop. He declared last July that after a spiritual journey to Jamaica, he was no longer a Dogg, but a Lion. Not only that, but his three-decade stage persona would be changed, effective immediately. “I have always said I was Bob Marley reincarnated,” Snoop told reporters at a news conference. “I feel I have always been a Rastafarian. I just didn’t have my third eye open, but it's wide open right now.” Oh-kay...

12. Alec Baldwin Grabs Cameraman --Twice!

You'd think that Alec would be used to paparazzi at this point, but apparently not. He got into two separate altercations with photographers last June, allegedly punching one outside of a courthouse and then squeezing the arm of a separate camerman just two weeks later. "I want you to shut the f*** up ... leave my neighbor alone ... get outta here," yelled Alec to the second photographer. Yikes! Fortunately, he didn't face any criminal charges for the incidents.

13. Randy Travis's Naked DUI Arrest

Throughout his nearly 35-year career, the country music legend has sold over 25 million records, churned out 22 No. 1 hits and won a Grammy just two years ago for I Told You So, his duet with Carrie Underwood. He was also arrested for drunk driving in the nude last August and provided police with what might be the most epic mugshot of 2012. Unfortunately, all signs are pointing to a serious drinking problem. Here's hoping he gets well soon. 

14. Donald Trump's $5 Million Challenge to Barack Obama

At the beginning of 2012, we thought Donald was just a publicity-loving, eccentric businessman with a silly reality show that involved firing the likes of Gary Busey. But after his "very, very big" announcement consisted of a $5 million challenge to Barack Obama to release his passport and college applications, he officially became a joke that not even the most staunch Republicans can respect. Even his own children reportedly told him to chill out. It will be interesting to see if his bad behavior results in bad ratings for the upcoming season of Celebrity Apprentice.

15. Rihanna and Chris Brown's Love Triangle

Fool me once, shame on you. Fool me twice...post your frustrations on Twitter for the world to see. RiRi and Breezy started looking cozy again this year and Chris even dumped his girlfriend Karreuche Tran to give things a second shot with Rihanna. The problem is that he can't seem to make up his mind and has been spotted out and about with both of them. Meanwhile, Rihanna seems to revel in the fact everyone hates their relationship and has repeatedly tweeted pics of them in compromising positions before venting her frustration over his behavior. It's immature, junior-high behavior from both of them that shows no sign of slowing down.

16. Everything That Lindsay Lohan Did in 2012

Liz and Dick. Car crashes. Nightclub brawls and arrests. Lindsay has an amazing way of begging people to give her another chance and then completely ruining the opportunity. Unfortunately, we think her nine lives in Hollywood have finally run out.

17. Amanda Bynes's DUI Tweet to Obama

Amanda isn't the first person to be charged with a DUI or deny it, but she's definitely the first person to tweet the President about it. "Hey @BarackObama... I don't drink," she wrote. "Please fire the cop who arrested me. I also don't hit and run. The end." Somehow, we imagine he had more important things to do that day.

 

Okay, that does it. Does your face/palm hurt from all the facepalming you just did on these celebrities' behalves?
