My husband is leaving today to head up north for the start of deer hunting season. Of course he referred to the movie "Escanaba in da Moonlight" many times as we were packing his gear. (If you haven't seen the movie it is about a hunting camp and it is filled with farting and bathroom humor!) Next weekend he is heading to a hunting camp in the UP, so I'm sure I'll be regaled with more fart humor than a girl can stand in the next couple of weeks.
My grandson is just turning 3, and I am sorry to say that one of his first words when he was learning to talk was "fart". It starts so young! I think you are right Boomer, it's in the chromosomes.
