Watch Paul Rudd Laugh Really Hard in His 'Saturday Night Live' Promos

Just when you thought it wasn't possible for Paul Rudd to get any more adorably charming, he went ahead and filmed these goofy 'Saturday Night Live' promos with his 'I Love You, Man' costar (and 'SNL' cast member) Andy Samberg.

Our favorite is the one where he laughs really, really hard -- like, really hard -- but the Santa cameos are pretty great too. Rudd is currently promoting his romantic comedy with Reese Witherspoon and Owen Wilson (and Jack Nicholson!), 'How Do You Know.'

Get psyched for tomorrow's Paul-stravaganza (with host Rudd and musical guest Paul McCartney) after the jump.
