I like how he went to a poker night and figured out he's good at blackjack. Sounds like his friends wanted to gift him some money even though the idiot couldn't even figure out what game they are playing.
I see people latch onto that detail. I find it plausible that some guys having a "poker night" might play other card games in addition to poker. Play a few hands of 5 card draw, some 7 card stud, maybe a round of blackjack or two.
