well, when you sit on the toilet, the way the seat is set up, you sink down the slightest bit and it spreads them for you, realize it next time you sit down.
the real question is, how the hell does the toilet withstand these huge people? I know if I wiggle around a little it feels like the seat will break off, how many seats are these people going through?
and 38 waist is a touch large, I feel fat if I have to buy 36 waist. and you're 3 inches taller and only 5 lbs more (if even).
