McDonald’s probably hasn’t seen a more dedicated customer since the guy who ate Big Macs every day.

A Norwegian teen says he took some ribbing from his friends about his reputation with the ladies and they imposed a peculiar punishment on him: either get a Barbie tattoo on his backside, or the McDonald’s receipt on his arm. Stian Ytterdahl says he chose the receipt, although he may regret it when he’s older.

“Now I’m a living billboard, but I think it’s all just fun,” he said. “Maybe it won’t be as fun when I’m 50 or 60 years old, but that’s my choice.”

Ytterdahl is using his newfound fame to become well-known across social media, starting a Facebook page dedicated to his odd tattoo. And now, he has another receipt to add to his collection: the one from his tattoo shop visit. That one went on the other arm.
