I would be....

A little kid walks into a city bus and sits right behind the driver and 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 continues with, ''If my dad was an elephant and my mom a girl elephant I would be a little elephant.''

The kid goes on with several animals until the bus driver gets angry and yells at the kid, ''What if your dad's a drunkard and your mom's a prostitute?!''

The kid smiles and says, ''I would be a bus driver!''
