I know someone did this a year ago but I liked it and I don't think the thread is around anymore.
Here's how you play: Someone posts a riddle, whoever gets it right gets to post their own riddle, and it continues that way.

You are in a room with 4 walls. There are 4 windows on each wall. Each window points toward south. A bear walks by. What is the color of the bear and why.
