A conversation between a little boy and a teenage boy.

“Dude, what is a pimple?” – Little Boy

“A pimple?  It’s a small infection in the skin caused by the blockage of a pore.  Pores are things that produce oil on your face.” – Old Boy

“Really?  I thought it was a type of dog.” – Little Boy

“Dog?  Ha, ha.  No little buddy.  You are thinking of a ‘pit bull’.  That is a type of dog.” – Old Boy
