Two young boys walked into a pharmacy one day, picked out  a box of tampons and preceded to the checkout counter.
 
The man at the counter 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, 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.”  
 

Truth in advertising never thought about this!

LOL thanks
