Can anyone in late night get along?

It's no secret that Jay Leno has pissed off most of his competition, but he's not the only late night host with a grudge. Notorious loudmouth Chelsea Handler got into a verbal sparring match with David Letterman while appearing as a guest on his show. She called him a "small man" and it all went downhill from there...

Luckily, Dave is a New Yorker and can trade potshots with the best of them. He and Chelsea traded insults in what was easily one of the funniest moments of the year on his show.

"Do you ever have moments like this on your show when you know it's going nowhere? What do you do when that happens?" cracked Dave.

Chelsea managed to get in another barb at Dave's appearance by calling him "dainty," but he fired right back by referring to her as "kinda hefty for a broad."

Of course, this isn't the first time Chelsea has gotten into it with a late night host. Just last week, she slapped around Conan O'Brien while the pair were naked in the shower as part of a sketch for Chelsea Lately.

Check out the hilarious riffing between Chelsea and Dave below!
