Oldie, but goody

A bloke is in a queue at the Supermarket 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 may be the father of one
of my children!”

His mind shoots back to the one and only time he has been unfaithful,
Christ!

So he replies "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

some wet celery and stuck a cucumber up my arse!?"

[scroll down]

No she replies coldly,“I’m your sons’ English Teacher”…

LOL… heard a variation on this, but like it all the same!
