I used to beleive as a kid that doing a pooh was a guy thing and that girls just didnt pooh. I held this belief right up until my 18th birthday when the morning after the night of heavy drinking before my sister came out of the bathroom and (as a joke) said she had just done 'a big grog bog'. I was totally floored and thought she was just kidding around. I replied 'yeah right as if you could you are a girl'.
I have never lived it down with all my mates when it was revelaed that this is what I seriously thought right up unitil I was 18.
