A little kid walks into a city bus and sits right behind the driver.The little kid starts yelling, "If my dad was a bull and my mom a cow I'd be a little bull." The driver starts getting mad at the noisy kid, who continued with, "If my dad was an elephant and my mom a girl elephant I would be a little elephant."

The kid went on with several animals until the bus driver got angry and yelled at the kid, "What if your dad was a serial killer and your mom was a prostitute?!"

The kid smiled and said, "I would be a bus driver!"
