Free Tatoo

A man walks into a tattoo parlor and says he would like a $100 dollar bill on his dick. Well the tattoo artist laughs and says "I'll do it for free if you can give me one good reason for it."

The guy thinks for a second and says. "Well one, I like to keep my money in my pants, two I like to watch my money grow, and three I want to see how fast my wife can blow a $100.
