Biff Henderson from 'Late Show With David Letterman' (weeknights, 11:35PM ET on CBS) paid a visit to the set of 'Cop Out.' He hung out with Bruce Willis and Kevin Smith, but nobody got a word in edge-wise with Tracy Morgan holding court.

Let's see, he covered a pivotal scene from 'Planet of the Apes,' his favorite movie ('Shaft'), his least favorite movie ('E.T.'), his biological mother (Katharine Hepburn), losing his virginity at the age of six, Marion Barry, and e-Harmony.

And we're sure there were a few more Easter eggs hidden in there.

Watch the video after the jump.

Maybe I'm just such a guy, but I love blooper and practical joke shows. When actors screw up and live news reports go horribly wrong. That's why I laughed so much at this clip from last night's Late Show with David Letterman. It's not the lame hidden camera jokes that Biff Henderson tries to play on people, it's that he can't get the name of the segment right. I find that funny (Biff is always funny anyway).
