Last night Late Show host David Letterman gave Taylor Swift "the most unique compliment" she's ever received when he told the lovely songstress that he thought she smelled like expensive wood. Yes, wood. After struggling to explain what in the hell he was talking about, Letterman gave up and begged Swift for a fist-bump, thus avoiding a revenge track on her next album. Over on the Tonight Show, Robert Downey Jr. just wants to make it clear that he's never done anything lewd to himself with a garden hose, and Milla Jovovich comments on Chelsea Handler's "prickly" Twitter persona, on Chelsea Lately. Last but not least, Joan Rivers drops by Late Night with Jimmy Fallon to announce that she's engaged! Not. Watch our compilation to see what you missed.
