Chess Impairment

Okay, listen up, buttercup. This joke is dark. Like, really dark. It's saying Americans can't play chess because they lost the "2 towers." That's a reference to the 9/11 terrorist attacks on the World Trade Center. It's messed up because it's making light of a really tragic event where a lot of people died. Also, you probably can't beat me in chess, because you are a fool.
