A guy goes to the tattoo parlor and offers the tattoo artist $1,000 to
put a $100 bill on his willy. 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
tattoo if he would just tell the reason for putting a $100 bill on his
willy.

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!
