NEW YORK — Did someone really write banter for Adrian Grenier to sleaze on Mischa Barton? Because if so, that's weird.

All of a sudden, Megan Mullally is on crutches: that's what you get for doing a musical number with Donald Trump!

David Letterman comes out, and nearly gets a standing ovation. But does Conan O'Brien look kind of annoyed?

Letterman does the Johnny Carson tribute. (I know Letterman and Carson were close, but do you think Jay Leno was considered for this job? He did, after all, inherit the "Tonight Show," no matter how Carson felt about that.) A Carson montage follows, including his singing with Bette Midler and his last "good night."

More tears.
