Off the charts, baby! I think it might be, like, 302, or something. At least that's what Wii Fit said the last time I used it, fat lot of good it did me. To be fair, I'm fat as hell, know it, and kinda don't care, so we're just splitting hairs here.
Honestly though, I'm surprised that the GB community is in as good a shape as it is! It's good to know not all nerds are hugely overweight.
