A couple is watching a TV series.
A hag comes before the King and Queen, tells the King that she is really the Queen, and that her shoul had been moved into this body, that of an old, ugly revolting witch.
The wife asks the husband, "Would you still love me if I were old, ugly and revolting?"
"Of course I would, dear," he says.
Something in the way he said it made her smack him up the backside of the head.
