Quote from Eric in Substitute
Mitch: You know, Mr. Forman, I learned a little about cars from my uncle who used to fix tanks in Vietnam. Now that's hero's work, fixing machines that kill people you don't agree with. My only regret is that I haven't had a chance to fight for my country. Red: Really? Eric's only regret is that he doesn't live in space. Eric: That's not my only regret. It's just one of them.
