Boo! Rusty cheats: I really do it. I push a quarter through the rings I'm wearing and it's size 11 or much less in diameter than the quarter. And I drop a quarter through a piece of 1/2" pipe without it touching the sides and yes it really goes through it - just hold the quarter ~0.312" above the pipe and drop it and while holding your mouth right it'll fall though. I accept paypal.
