After finding internet fame with their outrageous breakfast offering, a food van has now created a monster challenge that appears unbeatable.
Rolling Rolls, who were behind the monstrous full breakfast in a whole loaf of bread, are now welcoming customers to take on their latest challenge.
But this one is not easy — far, far from it. No one has been able to finish it — and you'll see why.
It's called the Fat Boy Challenge - after the Harley Davidson Fat Boy, because of the food van's new Cardiff location - and it is made up of approximately two and half pound of meat.
Overall the burger weighs more than three pounds and it includes 24 ounces of beef (the burgers), cheese, four sausages, four large fried eggs and 12 onion rings all sandwiched in a massive tiger bread roll.
And if that wasn't enough, it comes with a portion of chips on the side too.
Customers get 20 minutes to finish it and if they do, they won't pay a penny.
However if they fail - which everyone has so far - they've have to cough up the full price of £15.
Owner of Rolling Rolls, Dan Preston, says the closest anyone's come so far is when a customer did finish the meal - but in 34 minutes, not 20.
An impressive feat by anyone else's standards - but Dan is strict on his 20-minute ruling.
After the success of Rolling Rolls' breakfast challenge, the owners wanted to try something new after moving to a new location four weeks ago.
Dan, 37, who's a fan of food challenges, said: "We did the breakfast in bread before and that was a huge success, and we've had relocate so we've come up with this idea to boost things.
If you reckon you could take on the challenge Rolling Rolls, which was previously in Bridgend, is now found at Glynstell Park, near Cardiff Harley-Davidson
