A little kid gets on 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 was a drunk and your mom was a prostitute?!''

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