God,that's funny.
I've always wondered about what prompts people to go into certain professions. At what point does a medical student decide "Hey, I want to be a proctologist." Or, what goes through the mind of someone who wants to become a Corrections Officer? ("Hmm... Locked up all day long with hundreds, if not thousands, of murderers, rapists and other assorted scum who would love nothing more than to stick a shiv in me. Where do I sign up!")
