well i mean we could only go on honesty.... but ther would be rules.... the joint would have to be lit like a normal joint, and you make the bigger cherry by lung power alone... and there would have to be some sort of size.... cuz you make a pencil lead size joint, it's going to get a very big cherry... you make a roll of dimes size joint, it's goign to have a shorter (but wider) cherry...

it's just an idea tho...
