So I'm having fun in class answering riddles on the Hobbit website. It makes me think such a game would be fun here. Here are the rules. Ask a riddle. Everyone can guess, but please no one cheat and look it up. Since a person can't always respond if it's right or wrong, I suggest that people post riddles whenever they want as well. I'll go first with my favorite straight from The Hobbit:

Alive without breath
As cold as death
Never thirsty, always drinking
All in mail, never clinking

What am I?
