This is one extremely odd thing to think up.
Basically, you place skittles or cheerios on a treadmill before you turn it on.
Then you lay on your stomach and someone turns it on and that's when you go to town trying to catch as many as you can in your mouth.
Very random lol.
I'd have to pass just because of the nasty feet and sweat that has touched the treadmill before you got to it..
