Do you love a good burger? So much so that you’d get one permanently inked on your body? Then this Australian restaurant has a deal for you. Café 51 in Melbourne will give customers free burgers every day for life if willing to get a full-sized tattoo of one off their menu. According to the restaurant co-founder, six people have already gone through taking them up on the offer, so he’s started a registration page that has received over 3,000 applicants. The only catches: you’ll have to pay for the tat yourself and it has to be true to size. What’s the wildest burger you’ve eaten? How about the strangest tattoo you have?
