A few of mine: I was 13 when I saw IT'S A MAD, MAD, MAD, MAD WORLD at the Boston Cinerama Theater, and with all the audience laughing around me, it was easy to find this movie absolutely hysterical. Especially funny: Jonathan Winter's destrcution of the gas station. THE GROOVE TUBE. The moment I realized what I was looking at during the "Public Service Announcement" at the end, I lost all composure, dropped an entire boxfull of Milk Balls out onto the floor, and was on my back on between the seats. Couldn't get my breath. Hadn't happened before that and hasn't happened since. WAITING FOR GUFFMAN. The end credit sequence, and the MY DINNER WITH ANDRE action figures gag. I may have been the only one laughing, and maybe the fact that it was such an in-joke made it seem all the funnier. What are YOUR biggest movie laughs?
