The 1990 crime saga Goodfellas, from the great Martin Scorsese, is widely regarded as one of the best motion pictures ever. Adapted from the 1986 nonfiction book Wiseguy, about Henry Hill and the rise and fall of the Lucchese crime family, the film offers the best performance of Joe Pesci’s career. Pesci costars as Tommy DeVito, a hotheaded member of the Lucchese family. In one of the most memorable scenes, Tommy is telling a funny story that has the entire gang, including Henry Hill (Ray Liotta), in stitches. When Hill says, “You’re really funny,” Tommy seemingly loses it, replying, “I’m funny how, I mean funny like I’m a clown, I amuse you? I make you laugh, I’m here to fuckin’ amuse you? What do you mean funny, funny how? How am I funny?” The scene was completely improvised by Pesci and Liotta in rehearsals, and is based on an incident rumored to have happened to Pesci while he was a youngster working at a restaurant. Pesci is said to have told a mobster he was funny, and the mobster became very angry.
