My ex son-in-law could make me belly laugh more than possibly anyone else I've ever met with his truly stupid unexpected jokes. E.g. "I can't get over it" says him, with a big sigh. "What?" says me, all concerned. "That 20ft wall" says him, totally deadpan. I'm laughing now writing this although I know it's funny only to me probably, in fact my daughter used to shake her head in amazement that I found him so funny. Fortunately, his son, my oldest g'son has inherited much of his Dad's daftness and he can make me belly laugh at the most unexpected times.
