Annoying Boy On Bus

Little Johnny 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 Little Johnny , who continues with, ''If my dad was an elephant and my mom a girl elephant I would be a little elephant.''

Little Johnny goes on with several animals until the bus driver gets angry and yells at Little Johnny , ''What if your dad was gay and your mom was a prostitute?!''

Little Johnny smiles and says, ''I would be a bus driver!''
