A guy goes to the tatoo parlor and offers the tattoo artist $1,000 to put a $100 bill on his willie. The artist agrees, but is curious and asks the man why he wants to do this.
The man replies, "I have my reasons which I would rather not tell right now."
So, the artist goes ahead and does the job. But, all the while he is anxious with curiosity over why this man wants a $100 bill on his penis.
So, he tells the man that he really needs to know the reason why and says that the man can keep the $1000 he would have paid for the tatoo if he would just tell the reason for putting a $100 bill on his willie.
So, the man consents and offers these three reasons: "First, I like to play with my money. Second, I like to watch my money grow. And third, and most importantly, the next time my wife wants to blow $100, she can stay home to do it."
