The movie: Caddyshack (1980)
The player(s): Rodney Dangerfield

Though man child movies are littered with hundreds of flatulence-related funny business, it's not difficult to pick the one joke to highlight. It comes from Harold Ramis' classic Caddyshack, in which country club misfit Al Czervik (Dangerfield) breaks the stuffiness—and the silence—of a fancy dinner when he lets one rip and asks: "Whoa, did somebody step on a duck?"
