A woman goes to the doctor complaining that two green
marks have appeared on the inside of her thighs.
“Mmm,” says the doctor, puzzled, “now what can that be…”
He thinks for a while and then a smile crosses his face. “You
don’t happen to go out with a gypsy, do you?” he asks.
“Why, yes, I do.”
“Well, that’s the answer. Tell your boyfriend that his earrings
are not real gold!”
