If you love food challenges, you'll know that the most intense ones can feel like the ultimate test of both body and mind. There are plenty of contests out there, involving steaks, burgers, pizzas, pasta and virtually any food that you can think of, with the restaurant usually having a Hall of Fame section for those brave (or foolhardy) enough to complete their incredible tasks.
But one restaurant in Las Vegas boasts arguably one of the world's hardest challenges. The Heart Attack Grill was set up with the sole intention of creating 'nutritional pornography' and food that's 'so bad for you it's shocking'.
The brave LADs from Unplanned America tried their hand at the restaurant's notorious Bypass burgers - check out their attempt below:
The menu has several burgers, ranging from the Single Bypass Burger, all the way up to the Octuple Bypass Burger. The mid-level Quadruple Bypass Burger has nearly 10,000 calories and consists of four-half-pound beef patties, 20 strips of bacon, eight slices of American cheese, a whole tomato and half an onion served in a bun.
Fries are also included with the artery-clogging goodness, which are deep-fried in pure lard. Wait, what?
As a part of the gimmick, diners are asked to dressed in hospital gowns upon entry, waitresses wear nurses' uniforms, wine is distributed from an intravenous drip bag and, once they're done, well-fed (and most likely exhausted) patrons can exit the restaurant in a wheelchair that comfortably fits two.
But one of the main conditions to taking on a Bypass challenge is that if you don't finish your meal, your waitress is permitted to spank you with a paddle three times.
And she does not hold back.
The restaurant has also courted a bit of controversy in its 12 years, with one man dying from a heart attack four years ago. John Alleman was a daily customer and an 'unofficial mascot' of the brand, but unfortunately collapsed while waiting for a bus outside the restaurant.
Another man suffered a heart attack while eating a Triple Bypass Burger in 2012 - the worst part being that other diners thought it was a part of a stunt and pulled out their phones to film the incident.
Restaurant owner 'Doctor' Jon Basso told Fox: "I actually felt horrible for the gentleman because the tourists were taking photos of him as if it were some type of stunt. Even with our own morbid sense of humour, we would never pull a stunt like that."
But even bearing in mind these sobering tales - and that's without even getting into the mind-boggling calorie count - it appears there's no shortage of people willing to take up the challenge.
