In the wild Delta house, pledges were initiated into the fraternity by being assigned a funny name, having beer poured on their head and drunkenly singing "Louie Louie". In Omega house, the pledges were hit on the butt by a paddle-wielding Niedermeyer and had to say "Thank you sir may I have another!" after being smacked. This line, probably one of the most famous and frequently repeated lines of this movie, was uttered by a then-unknown Kevin Bacon.
