If anyone was curious about what Stian Ytterdahl orders at McDonald's, look no further than his right arm.

Ytterdahl tattooed a McDonald's receipt on his arm after his friends dared him to do it.

The 18-year-old Norwegian tells the newspaper Romerikas Blad that his friends were sick and tired of his luck with the ladies. They dared him to get a tattoo of Barbie on his posterior or a McDonald's receipt on his arm. He chose the latter.

Ytterdahl's receipt tattoo includes an order for a cheeseburger with three extra toppings, a soda and a McFlurry. The tattoo includes the whole receipt -- store number, phone number, date and time of purchase.

According to CNN, McDonald's Norway addressed the viral story.

"[It's] not a marketing stunt and not an employee," said Margaret Brusletto, spokeswoman for McDonald's Norway. "[He's] a very loyal customer."

Ytterdahl already has similar plans for his left arm.

Sabelink Tattoo, the shop that gave him the McDonald's receipt tattoo, has offered to tattoo the receipt they gave Ytterdahl on his left arm for free.

Ytterdahl said he plans to take the shop up on its offer.
