@Sturgis,
I suppose I should really post this on the bad jokes thread, but your comment reminded me so here goes:
This fellow had been trying to seduce this young woman for a long time. She finally indicated a willingness to cooperate but on one condition -- he had to take her on an ocean cruise. He said, no prob, consider it done, we sail on the next departure date, etc.
Small problem. He'd been to sea once and knew that he was very susceptible to sea sickness. He went to his local drug store and ordered (1)a thick packet of condoms and (2) a bottle of anti-nausea meds. The drug store clerk looked at him in pity and said, "Look, if it makes you sick, why do you do it?"
