Proving that fate has a macabre sense of humor, a man dining at the poignantly named Heart Attack Grill in Las Vegas suffered an apparent heart attack. He was eating what's known as the Triple Bypass Burger, a 6,000-calorie burger that includes three beef patties, cheese, onions, tomatoes and "special sauce" on a bun.

The eatery, which boasts "taste worth dying for," includes other menu items such as Flatliner Fries and Butter-fat Shakes, served by waitresses dressed as nurses.

Customers initially thought that it was a publicity stunt, but Heart Attack Grill owner Jon Basso confirmed that it was not, telling MSNBC, "We would never pull a stunt like that."

Thankfully, he survived and is recovering.

Video a fellow diner took of the customer being wheeled out by paramedics that went viral.
