Teenage Humor
One day, two teenage boys, around 13 years old, walk into a gym. One of the boys go towards a pull up bar.The boy is short and can't reach the bar.
So, he jumps up and grabs it and starts to do pull ups
As the boy was doing pull ups, the other boy comes up to him and says "Be careful! If you don't have a good grip, you could fall and hurt yourself."
The boy who is doing pull ups turns to the other boy, grins and says "Don't worry! I have a good grip; I'm well hung."
