A bloke is in a queue at the Super Market when he notices that the rather
dishy blonde behind him has just raised her hand and smiled hello to him.
He is rather taken aback that such a looker would be waving to him, and
although familiar he can't place where he might know her from, so he says
"sorry, do you know me?"
She replies "I maybe mistaken, but I thought you might be the father of
one of my children!
His mind shoots back to the one and only time he has been unfaithful,
Christ! he says "are you that stripogram on my stag night that I shagged
on the snooker table in front of all my mates whilst your mate whipped me
with wet celery and stuck a cucumber up my butt?
No she replies, I'm your sons' English Teacher
