"Humor, if we are to be serious about it, arises from the ineluctable fact that we are all born into a losing struggle. Those who risk agony and death to bring children into this fiasco simply can’t afford to be too frivolous. (And there just aren’t that many episiotomy jokes, even in the male repertoire.) I am certain that this is also partly why, in all cultures, it is females who are the rank-and-file mainstay of religion, which in turn is the official enemy of all humor."
