Two young boys walked into a store one day, picked out a box of tampons and proceeded to the checkout.
The cashier asked the older boy, "Son, how old are you?"
"Eight," the boy replied.
The cashier continued, "Do you know what these are used for?"
The boy replied, "not exactly, but they aren't for me. They're for him. He's my brother. He's four. We saw on the TV that if you use these you would be able to swim and ride a bike. Right now, he can't do either."
