Those crazy guys over at SportsPHDs.com (and believe me, they're crazy, check out their Batchelor Party!) recently tried their hand at a Supersized Burger. It's the 2lb Burger Challenge at the Painted Parrot, West Allis, WI. The Challenge: Finish the burger. The Prize: nothing from what I can tell, although there is of course the prestige and boasting potential to your friends!
[Updated 22 Apr 07] - Turns out there is a prize - a free quarter barrel party and food! (Thanks to SportsPHDs.com for the update!)
