PD62-63. Sticking out

There once was a man named Sir Lancelot
When he went out to parties he'd dance a lot
When making a pass
At a young pretty lass
The front of his pants would advance a lot!

There once was a fellow from Boston
Who drove a diminutive Austin
It had room for his ass
And a tankful of gas
But his balls dangled out, and he lost 'em!
