A little boy says to a bus driver, "If my mum was a cow and my dad was a bull then I would be a baby cow".

Then he says, "If my mum was a sheep and my dad was a sheep then I would be a baby sheep."

Then after he says more and more and the bus driver gets mad and says "Well, what would you be if your mum was a stripper and your dad was a drunk?" "Then," the little boy says, "I would be a bus driver!"
