- The inability to control a really odd British-like Brooklyn accent.
- Eating lunch in the Wien dining hall, despite years of consistent food poisoning.

- Inability to control the impulse to tell embarrassing anecdotes about Goldberg's retarded antics freshman year.
- Letter-writing campaigns to Congress.
- Age of Empires.
