I think, of anyone we've ever seen on the podcast, I'd most want to meet BBoy360.
I wouldn't want to actually be friends with him, mind you, but if I met him at a party I'd be around him all night. He's stupid, but he seems friendly, and the sort of obsessive who probably knows enough about his subject to remain interesting to talk to while having just enough social graces to connect with on some level. Contrast with Patrick82 for example; he's probably just as weirdly fascinating to talk to, but he's not socially capable enough that you'd really enjoy doing it.
