" A sense of humor is a serious business; and it isn't funny, not having one. Watch the humorless closely: the cocked and furtive way they monitor all conversation, their flashes of panic as irony or exaggeration eludes them, the relief with which they submit to the meaningless babble of unanimous laughter. The humorless can programme themselves to relish situations of human farce or slapstick — and that's about it. They are handicapped in the head, or mentally 'challenged', as Americans say (euphemism itself being a denial of humour). The trouble is that the challenge wins, every time, hands down. The humorless have no idea what is going on and can't make sense of anything at all. "
