You gotta admit that it is a bit funny considering things can be mildly disgusting. Considering the physiological response to disgusting things, you either upchuck or you don’t. Sure, you can feel the urge, but again, you still reach a point where it’s too much or not enough. It’s more of an on the fence thing, and not a continuum, like comedy.
Still, the concept is more than worthy of a strong community backing it up. And, well, some of it is definitely more disgusting than just mildly, so be warned.
