A guy gets home late one night and his wife says;
"where the hell have you been?
"I was out getting a tattoo."
"A tattoo? What kind of tattoo did you get ?"
"I got a hundred dollar bill on my penis."
"What the hell were you thinking ? Why did you get a hundred dollar bill on your penis ?"
"Well, number one, I like to watch my money grow...
Number two, once in a while, I like to play with my money...
And lastly, instead of you going out shopping, you can stay right here at home and blow a hundred bucks anytime you want."
