Tattoo on dick

A man goes to a tattoo artist and says: "I'd like you to tattoo a one-hundred dollar bill onto my dick."

The tattoo artist is surprised: "Well, that could hurt a lot. Why would you want a 100 dollar bill on your dick?"

The man answers, "Three reasons:
I like to watch my money grow
I like to play with my money
And next time my wife wants to blow a-hundred bucks she won't have to leave the house!"
