IWouldn't have come here.....!

[Bubu Msemaovyo]

A guy goes to the supermarket and notices an attractive woman waving at him. He walks over to her and she greets him warmly. He's rather taken aback because he can't figure out where he knows her from. So he says, 'Do you know me?' To which she replies, 'I think you're the father of one of my kids.' His mind races back to the only time he has ever been unfaithful to his wife and says, 'Are you the stripper from the bachelor party that I had sex with on the pool table, with all my buddies watching, while your partner whipped my ass with wet celery?' She looks into his eyes and says calmly, 'No, I'm your son's teacher.

It is the unexpected twist in the joke that makes it an exceedingly funny one.
