I've lived in quite a few places and sampled a lot of burgers and burger joints. The largest burger I had heard of was called the 4x4, available at California's famed In N' Out Burger. But it looks like Wendy's has just upped the ante. The gargantuan "T-Rex burger" boast a massive amount of meat with 9 patties plus fixins. Although its only available in Brandon, Manitoba, Canada and it's not officially "on the menu". Some how,  I have a feeling it soon will be. I'm also going to guess it'll come with a defibrillator too, but only if you buy it in a combo meal.
