My S.I. Law is proud that in nearly forty years of marriage, she has never farted in front of her husband.
That must be either because she runs round behind him and drops one, or she lets him fart first.
The funniest K.Hall fart I heard was when a few of us young Bros were waiting to use one of the urinals, and a Bro in his 60's was happily peeing when he let a real Rip-Roarer go, and he blithely said " 'scuse me" with no apparent embarassment, good for him.
