Probably my favorite theme for a con: Whodunnit?

Gratuitously ripped off from a really awesome movie.

Wadsworth: Professor Plum, you were once a professor of psychiatry specializing in helping paranoid and homicidal lunatics suffering from delusions of grandeur.
Professor Plum: Yes, but now I work for the United Nations.
Wadsworth: So your work has not changed.

If you see this at the con, please say hi to the friendly cat!
