The pepper challenge? Eat a whole pepper.. mayonnaise challenge? Eat a whole spoonful of mayonnaise..The cracker challenge? Get a plate full of crackers, with peanut butter on them and see how many you can eat, with your hands behind your back.(:
Saltine challenge, bread challenge, chubby bunny challenge... There's many. Look some up on the Internet for more ideas. I don't recommend doing the salt and ice challenge though... I did it once and got a second degree burn..
