I'm spending some time in Vermont this summer where i've been interviewing the locals about their 4 square rules. . .
here's a fun one to know and share:
Toilet Paper: You yell toilet paper, and roll the ball into any square. That person is required to sit on the ball (no hands!) to stop it's forward progression.
I personally haven't tried this one out yet, but assume it would lead to lots of falling down on your bum, and hearty laughs by all . . .
