Movie madness

On the first day of each semester, I ask my students to fill out index cards giving me their contact information and, for kicks, their favorite movie. It helps me remember their names. Take a kid I have this semester. We'll call him Bob. My whole life, I'll never forget what Bob's favorite movie was and, hence, his name. As I was going through the index cards (I do this in class, while everyone is there), I read aloud what his favorite movie is. It was Robin Hood: Prince of Thieves. I'm sure I couldn't control my astonishment. I'm sure my jaw dropped a little. What 20-year-old duuuuude has Robin Hood: Prince of Thieves as his all-time favorite movie? I'm waiting for the punch line. My faith in humanity hinges on it.
