"The cruise (sexual reference)" joke
A guy goes to a travel agent and tries to book a two-week cruise for himself and his girlfriend. The travel agent says that all the ships are booked up and things are very tight but he will see what he can do.
A couple of days later, the travel agent phones and says he can get them on a three-day cruise. The guy agrees and goes to the drugstore to buy three Dramamine and three condoms.
Next day, the agent calls back and says he now can book a five-day cruise. The guy says he'll take it and returns to the same pharmacy and buys two more Dramamine and two more condoms.
The following day, the travel agent calls again and says he can now book an eight-day cruise. The guy agrees and goes back to the drugstore and asks for three more Dramamine and three more condoms.
Finally, the pharmacist asks, "Look, if it gives you motion sickness, why do you keep doing it?"
