When Charlie Sheen and Maxwell Caulfield's characters are driving down Hollywood Blvd, Sheen yells at the window at a punk girl played by Christina Beck (who also was a punk in The Penelope Spheeris film Suburbia) The punk goirl yells back at Sheen "Eat my f**k!" Befuddled, Sheen sits back down and asks Caulfield "What doess'eat my f**k' mean?" This scene is a reference to the documentary, Decline of Western Civilization, made be penelope Spheeeris where the singer of the band FEAR shouts the line from the stage and his guitarist asks the same question Sheen asks.
