I was in the supermarket on the weekend and noticed an attractive woman
waving at me. I was puzzled and embarrassed because I couldn't place where I knew her from.
When I passed her I asked, 'Do you know me?'
To which she replied, 'I think you're the father of one of my kids.'

Now this really got the mind working, the only incident that I could
remember was at a stag party.

So I said:
'My God, are you the stripper from that stag party when we did it on the
pool table, with all my mates watching while your partner whipped my
???'


She looks into my eyes and says calmly, 'No, I'm your son's teacher.'
