If a corny line about a pun on the name of a magician is “sexual assault” - then no man is safe.
An old gag that was running around years ago involved asking a young lady to hold the guy’s thumb. He then produced a card which read, “I am a member of an alien race come to earth, whose sexual organs are located in the thumb of the male and the palm of the female. You have just engaged in coitus. If you enjoyed it, SMILE!”
He actually grabbed their butts. If it had been just the utterance of a joke that could easily be excused. I wonder if it isn’t the onset of dementia. Certainly is a plausible answer, and something to consider.
