EVERY unfunny con-goer who dresses as Deadpool. (Or other character who should be full of hilarity.) Could also be 'every Deadpool Lookalike On Champions Online' if Jacob (who is probably in the Deadpool costume) was a gamer, not just a comics and toy nerd (and sex addict, but that's tangential to this). I've run into several, myself, and probably passed more when I wasn't paying attention to the area they were in. Buggers are everywhere.

For Les's comment, don't read it as 'Shut up, person who I am calling Boobs (for no good reason, since you don't have them)', read it as 'Shut up, as I am no longer listening to you, since there are boobs'.
