Let it be said now: Paul Rudd doesn't give up. When he commits to a prank, he will ride that prank into the ground, and he will not back down.
Sure, he's probably super dedicated to acting and what not, but where he's truly ruthless in his need to have the last laugh. One could even say he's following in George Clooney's footsteps.
His latest foil comes at the expense of none other than television's Conan O'Brien. Loyal watchers of the late-night host will recall that Rudd has a little tradition whenever he comes on the show: Instead of playing a clip from the movie he is supposed to be promoting, he'll instead surprise O'Brien with a clip from the 1988 ET knockoff Mac and Me. Trust, it's way funnier than it sounds.
