Two young boys walk into a pharmacy one day, pick out a box of Tampax and proceed to the checkout counter. The man at the counter asks the older boy, "Son, how old are you?"

"Eight," the boy replies.

The man continues, "Do you know what these are used for?"

"Not exactly," the boy says. "But they aren't for me. They're for him. He's my brother. He's four. We saw on TV that if you use these you would be able to swim and ride a bike. Right now he can't do either one."
