The official Leverage convention has the best name of any convention ever.
I'm not going, because I don't have the time or the money, but I like to just bask in the sheer, unmitigated joy of that name from time to time.
(Really, the Transformers people dropped the ball. Come on, "BotCon"? How do you do an official Transformers convention and not call it "DeceptiCon"? Oh, the lost opportunities.)
