Ryan Seacrest FallsPrey to Sacha Baron Cohen’s Comedy Genius

Sacha Baron Cohen’s(Ali G, Borat, Bruno) newcharacter The Dictator arrived on the red carpet carring an urn that he claimedheld the ashes of Kim Jong Il. While he was being interviewed by Ryan Seacrest, he tipped the urnover, and accidentally-on-purpose spilled the “ashes” all over Seacrests’s tux.Seacrest was NOT amused, but Cohen’s joke was a perfect reminder that theOscars are supposed to be fun – weall take it a little too seriously at times. At least someone thought it wasfunny -- Seacrest’s E! colleague Kelly Osbourne couldn’t stop laughing!

Octavia Spencer’sEmotional Acceptance Speech

When OctaviaSpencer won Best Supporting Actress for TheHelp, her acceptance speech was not only emotional – it was funny, too! “Thankyou, Academy, for putting me with the hottest guy in the room,” she said,admiring her Oscar statuette. “I have to thank my families. My family inAlabama – the state of Alabama!” And when the “please wrap up” warning startedflashing, she said, “I’m wrapping up. I’m sorry. I’m freaking out!”

He joked about that fact in hisspeech, when he said to his Oscar, “You’re only two years older than me,darling. Where have you been all my life?!”

Emma Stone and Ben Stiller’sHilarious Presentation Banter

Usually those pre-scripted jokes the presenters have totell before announcing the category nominees are pretty stilted and awkwardlydelivered. But Emma Stone’spresentation banter with Ben Stillerwas hilarious! “This is my first time presenting an award!” she said, sweepingher hand out in a grand, I’m-so-wonderful gesture. Her over-the-top excitement aboutthe whole thing was a breath of fresh air.

Bret McKenzieWinning Best Original Song!

Aside from Melissa McCarthy, Bret McKenzie (member of Flightof the Conchords and songwriter for TheMuppets) was the nominee I was rooting for the most. And he won! His speechwas perfect – funny, endearing, and very sincere. “I was genuinely star struckwhen I finally met Kermit the Frog,” he said. “But once you get to know him,he’s just a normal frog. And like many stars here tonight, he’s a lot shorterin real life.” Bonus awesome moment: JasonSegel tearing up and applauding when Bret thanked Jim Henson.

The Cast of Bridesmaids Presenting the Short FilmAwards

The Bridesmaidsladies’ presentation of the short film Oscars was hands down one of the funniestmoments of the whole show. We caught on pretty early that Kristen Wiig and Maya Rudolph’s speech about “size” wasn’tjust about film length. “As my grandma used to say, it can be short and stillmake your toes curl,” Maya said. “And I believe in my heart that my grandma wasnot referring to wieners, but short films.” “See, I’d rather have a short filmwith some heft that’s nice to me,” Kristen responded thoughtfully. “Rather thana long film that just lies there and makes you do all the work.” Amazing.

Meryl Being Oh-SoMeryl

Meryl Streephas been nominated for 17 Academy Awards, and last night she won her third, forThe Iron Lady. The best part of herwinning was seeing her, once again, be the humble, little-old-me Meryl that weall love (and that Abby Elliott sobrilliantly taps into on Saturday NightLive). “Oh, come on!” Meryl said when she got to the stage. “Alright. Whenthey called my name, I had this feeling. I could hear half of America going, ‘Ohnooo. Oh, come on. Why her again?’ But whatever!”
