We had a fat cadaver in our anatomy lab too, although I wasn't part of the class that actually had to cut away at him. By the time my class saw him, he'd already been scraped down to the muscle. Which was hilarious, because you wouldn't know from a cursory glance that he'd been fat. It's almost like when you're 300lbs, your muscle and bone structure doesn't contribute to your being shaped like a deflated beach ball.
