Man enters a drugstore and asks the pharmacist for a pack of condoms. The Pharmacist asks, "What size?"
to which the man replies, "I'm not exactly sure." The pharmacist grabs something from under the counter and hands it to the man, "Well, take this board with holes, go to the bathroom and the hole your erect penis fits into is the correct size of condom for you." 20 minutes later the man comes back and tells the pharmacist, "I've changed my mind, I don't need the condoms. How much is this board"?
