Tony married one of a pair of identical twins.
A few months later, he was in court filing for a divorce.
“Would you tell the court your reason for wanting a divorce,” the judge said.
“Well, Your Honor,” Tony began, “periodically my sister-in-law would come over
for a visit and because she and my wife are identical,
occasionally I’d end up making love to her by mistake.”
“I understand they’re identical twins, but surely there must be some difference
between the two women,” said the judge.
“Precisely, Your Honor,” replied Tony “That’s why I want a divorce.”
