Let's address the elephant in the room. Whoever named this "The Impossible Big Mac Challenge" was overselling it a little. In a world full of competitive eaters with YouTube channels, you might have a tough time finding any food challenge that is genuinely impossible. (And even then, people are going to try.)
Nonetheless, the 7,480-calorie meal is obscene. It should be impossible. Or it should be forbidden. Outside of making like a toddler with its broccoli and proving what a good eater you are, you don't really need to eat four Big Macs, four large french fries, and four milkshakes in a day, let alone in under an hour. And that's the challenge, to eat all of that in under an hour.
It's making the rounds and competitive eaters are doing it in far less than an hour, as Matt Stonie highlights in the video above. Furious Pete put it all home in 24 minutes and 47 seconds. Leah Shutkever obliterated that time, by tucking it all away in 6 minutes and 15 seconds.
