Everybody knows how to play Jenga, right? The word "Jenga" is Swahili for "build," and the purpose of the game is to pull a brick from the base of the structure and add it to the top without making the whole thing topple over.
Here are some people my wife and I observed playing Jenga last night during an emergency run to our neighborhood brewery (they'd just tapped an ultra-rare keg of this). They understand one element of Jenga play, but are missing the point entirely. Did any of them ever stop and think, "Wait, what the fuck are we doing?"
I'll never know, because I rushed home for the start of Dayton-Stanford.
