A boy goes into a shop, grabs a box of tampons and goes to pay.The
cashier asks, "Are these for your mum?"
"No," says the boy, "not my mum."
The cashier says, "They must be for your sister then?"
"No," says the boy, "not for my sister,either."
The cashier is now curious, "Then who are they for?"
The boy says, "They're for my little brother. They say on TV, if you
wear one of these, you can swim and ride a bike, and he can't do either."
