Darn, missed out on this one earlier, and I have a personal experience with over-sized steaks.  About 40 years ago I was visiting family in central Alabama.  We had me, Mom and Dad, an uncle and a couple of cousins along.  Going north out of Birmingham while heading towards the lakes of northern Alabama, we happened to pass a place called the "Bug Tussle Steak House."  It was about lunch time so we dropped in.  As I recall, it was a "rustic Americana" type of place.
They had steaks on their menu in sizes 8 oz, 16 oz, 32 oz, and 64 oz.  The biggest steak was pretty expensive, but if you ordered a 64 oz steak dinner (which included a dinner salad and the USA's "French Fried" potatoes - but I know that they are really Belgian Fried...), and could finish the steak, fries, and salad in 1 hour, it was free.  The owner had maybe five pictures on the wall of people who had done this.
We ordered the 64 oz steak - but it was for the whole lot of us, not for just one.  That comes out to about 10 oz each, give or take a fraction.  We got it medium well, which by their standards meant "no pink in the middle but edges might be crispy."  As I recall, it was a good steak.
I have since heard from my cousins that the original owners were no longer there but the steakhouse still was.  The place is probably no longer as I remember it.
Just for the doubters who need to see links...
