Optical illusion tattoos have been making the rounds online recently, but this viral ink job will really make your jaw drop. It's not an MFA-designed masterpiece, but it is pretty unbelievable, and not in a good way. An 18-year-old Norwegian dude named Stian Ytterdahl just got a tattoo of his McDonald's receipt on his arm. Now that's someone who really loves Happy Meals.

Ytterdahl claims that his friends made him get the tattoo for being "too active with the ladies," according to Gawker, and the artists at Sabelink Tattoo were happy to oblige. They even offered him a free tat—the receipt for their McDonald's ink job on his other arm. Ytterdahl is set to go under the needle again on Monday.

"Now I'm a living billboard," Ytterdahl told Romereskes Blad, "But I think all this is just fun. Maybe it won't be as fun when I'm 50 or 60 years, but it's my choice."

McDonalds' thoughts on the tattoo? "We're obviously talking about a loyal customer."
