The name “Big Mac” leaves little to the imagination. Equipped with two beef patties, three pieces of bread, and a hearty slathering of special sauce, the burger has been McDonald’s signature item since it was invented by Jim Delligatti in 1967.

And though Delligatti died last week at the age of 98, the stars must have aligned right before his passing. Just a few short days before the fast-food innovator was laid to rest, the chefs behind Epic Meal Time succeeded in pushing the Big Mac to its limits, crafting a mammoth, 100-pound burger and redefining the term “Supersize Me” in the process.

Though last week we witnessed the evil geniuses behind Hellthy Junk Food create a gargantuan Chicken McNugget, Epic Meal Time may have succeeded in producing the largest Mac product known to man.

Though the entire process is thoroughly terrifying, watching the group churn a gallon of special sauce, or lay a doormat-shaped slice of cheese on two manhole cover-sized buns will likely scar you for the rest of your life. Proceed with caution.
