A Johnny walks into a city bus

A 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 kid, who continues with,

“If my dad was an elephant and my mom a girl elephant I would be a little elephant.”

The Little Johnny goes on with several animals until the bus driver gets angry and yells at the kid,

“What if your dad was gay and your mom was a attendant?!”

The Little Johnny smiles and says,

“I would be a bus driver!”
