A little kid gets on a city bus, sits right behind the driver, and starts talking really loudly.
"If my dad were a bull, and my mom were a cow, I'd be a little bull." he said.
The driver starts to get annoyed as the little kid keeps yammering on, "If my dad was a rooster, and my mom was a hen, I'd be a little chick."
The kid goes on and on with all the animals he knows, until the bus driver shouts back, "What if your dad was a bum and your mom was a drunk?!"
The kid smiles, and replies,"That's easy. I'd be a bus driver."
