Pick a door, any door. (Read intro)
So you and your friends are an abandoned circus and you hear a loud voice over a speaker it says "We haven't had visitors in ages! You better pick a door, that is if you want to live. MUA HA HA HA HA!" You guys are creeped out but promise to stay together. Then you see a big group of clowns and mines with chainsaws running at you!
You better pick a door. Enjoy.
