1 - 2 - 3 - 4, we declare a thumb war!
If you have a friend who always tries to pull a fast one on you during a thumb wrestling match, it's time you made your bouts official with a Pro Thumb Wrestling Arena ($7). Everything's on the up-and-up inside this ring and you'll finally know whose thumb is the true champion.
Why is it that thumbs like to fight so much? Perhaps it's 'cause they're opposable!
