Two young boys walked into a chemists one day, picked up a box of tampons and walked up to the counter.
The pharmacist asked the older boy 'son how old are you?'
'Eight' the boy replied
The man continued,'do you know what these are used for'?
The boy replied 'Not exactly. They're not for me, they're for him, he's my brother, he's four'.
'Oh really' the pharmacist replied with a grin
'Yes' the boy said. 'We saw on TV that if you use these you can swim, ride a bike and play tennis. Right now he can't do none of those.'
