I hope you upvote this reply (even though it's disturbing), but when I was 8 years old, I used to pick ALREADY-CHEWED bubble gum off the ground and start chewing it on the way to school so I'd look cool to the other kids in my class. Of course I never told them where I got the gum. And I was too young to realize why I kept getting canker sores in my mouth. lol
