Ok, I did forget the funniest one.
My father taught me "ding dong avon calling" when I was a child.
Well one day I stood up in church (dad did not attend in those days), lifted up my dress (yes I was a bit of an exhibitionist as a child) pressed my belly button and said a bit loudly "ding dong mommy, ding dong".
God only knows how much trouble my father got in for all the things he taught me.......
