This is the biggest McQuarter Pounder challenge I've seen. 10 quarter pounders, that's 2.5 pounds worth of 100% pure beef! I'm guessing a fair bit of that was grease though, you should see how much he manages to squeeze out onto the meal tray!

my buddy eats a custom quarter pounder with 10 patties ($15 cdn for this bad boy)
