A guy goes to a travel agent and books a two-week cruise for himself and his girlfriend. A couple days before the cruise, the travel agent calls and says the cruise has been canceled, but he can get them on a three-day cruise instead.

Guy says, “OK,” and goes back to the pharmacy and asks for three more Dramamine and three more condoms. Finally, the pharmacist asks, “Look, if it makes you sick, how come you keep doing it?”
