My son recently introduced me to lolcats via icanhascheezburger.com . Lolcats humor is like the first time you walk in on people reciting a Monty Python routine. Some of the jokes are immediately funny, but sometimes it feels like “Nobody expects the Spanish Inquisition,”—uh, I don’t get it. It’s only after repeated exposure that you begin to understand the rhythms and references. You have to learn the rules—the fonts, the spellings, the subgenres within lolcats—before you can see what’s so funny–or not. It’s another example of how much we humans love form. A sort of visual limerick. A game.
