For whatever reason, I kept thinking of The 40 Year-Old Virgin while watching The Hangover. It's a little unfair, but it's the gold-standard for me in terms of male-bonding comedy. I think this is one of my favorite comedic scenes in movie history.
From Jay starts throwing out the big phrases ("lets move forward amicably...") as Negroes are wont to do, and Kevin Hart's response, ("Because I don't understand em, I'm goin take em as disrespect,"), to the surreal braggadocio ("Nigger, we fuck dwarfs in the ass,") to pulling in Andy ("Yeah nigger, we will both mash you!") to Kevin Hart's hand signal and retreat.
"Now you've found yourself a nigger. You was looking for a nigger? Nigger hear now..." All awesome-sauce. I swear they were thinking of me when they made this scene. I was hoping that Apatow would do something with Romany Malco. He killed in this movie.
