Circus Bear

A boy and his dad go to the circus, and while they're there they see a bear riding a bicycle.  

Fascinated, the boy asks his dad, "Dad, how do they teach that bear to ride a bike?"  

The dad replies confidently, "Well, that's easy son.  

They just nail his feet to the pedals and beat the shit out of him."

Keep training.  

Up, up, up.
