Sometimes the simplest idea is the best idea. If you're hungry, eat food. If you're thirsty, drink water. If you want a tattoo, get "tattoo." It all makes sense! This tattoo is hilarious. It's exactly my style of humor, which isn't exactly a compliment. "Want to see my tattoo?" / "Sure. What?" / "Tattoo." You can go in circles and circles with people. Your life will always be like a Monty Python sketch. Then one day you come home and your wife's stuff is gone... that's when the laughter stops.
I like to think that there's a specific story to this tattoo. A young man wanted a tattoo, so he asked his father. The father said he could get a tattoo, but only if it said tattoo. The kid took it as a challenge and now we have this glorious tattoo.
