A man wanted to find out if both his wife and mistress
were faithful to him. He decided to send them on the
same cruise, then later question each one on the other’s
behavior. When his wife returned, he asked her about
the people on the trip in general, then casually asked
her about the specific behavior of the passenger he knew
to be his mistress.”That woman slept with nearly every
man on the ship,” his wife reported. The disheartened man
then made a date with his cheating mistress and asked
her the same questions about his wife.”That woman was a
real lady,” his mistress said.  “How so?” the encouraged
man asked.”She came on board with her husband and never
left his side.”
