Little Johnny (eight years old) went into the drugstore and said to the pharmacist, "I'd like a box of Tampax, please."

"Sure," said the pharmacist, "Is it for your mother?"

"No"

"Well then, is it for your sister?"

"No, it's for my little brother. I saw an ad on tv that if you use these, you'll be able to swim and ride a bike, and he can't do any of those things yet."
