Tattoo Help?

My friend Frank is gay. He wanted me to come with him into our friend's tattoo parlor while her got a tattoo. He wanted to get a tat of a kangaroo right above his bottom. I paid my friend Daryl $400 to tattoo "Exit Only" with an arrow poitning down. He did and now Frank won't talk to either of us. Where is his sense of humor? Don't you think he is being a bit childish?
