Quoted from Tranquilize:

Any "guy" hobbies are full of mutants, stinkies and creeps. I joined a darts league and convinced my wife to come out and play on an open play night. She stayed for half the event. She just couldn't take the overweight, middle-aged men talking to her chest and calling her "lovie." We do rotating teams, so I was away from her for most of it.
Magic the Gathering has to be the funniest. Stinky comic shop mutants are the lowest of the low. Back when I played tournaments, there would be guys in sweat pants (like that guy that has that "museum" on here) that literally smelled like shit and onions. LOL. Then you have the little teenie bopper girls that would have to play them. It's a blast to watch a sewer rat attempt flirtation with a dove.
Pinball expos are pretty tame in comparison, although my wife has complained about mainsplaining of rules and innapropriate comments.
