The people I hold dearest are the ones who are funny for funny’s sake. They do bits without a microphone, they deliver punch lines silently to themselves, they joke around without any obvious reward. They are the bus driver who consistently responds to the question, “How much is the bus?” with a deadpan, “About two hundred and fifty thousand dollars.” They are the science teacher Photoshopping baby goats onto his wife’s birthday card, and the seven-year-old pulling a goofy face in the mirror that only she will see.
