The Anti-Riddle Game

First topic message reminder :

NOTE: THIS IS A THINKING GAME OF TWISTED LOGIC

The forum has been dead recently, so I'm attempting to revive it with a game I made. It might be too complicated though, so I don't know how long it will last.

The aim of the game is to find as many answers to one riddle as possible, no matter how ridiculous they are. It's basically a game about finding loopholes in riddles.

The asker can add restrictions to their riddle, but it must still be possible for the original answer to still apply. However, try to at least leave one "loophole" to make it fun.

The answerer can ask the asker to define certain words if they're too vague.

FOR EXAMPLE:

Riddle:
Mary's father has 5 children. Four of them, from youngest to oldest, are named January, February, March, and April. What is the oldest child named?

Answer(s):
1. Mary
2. April. Mary wasn't in the list of youngest to oldest so there was no way to know whether she was the oldest child or the youngest child. This leaves April as the oldest.

The person who creates the most answers wins and gets the next riddle. If it ties, the person who said the most first gets it.


I'll go first:
How can you physically stand behind your friend's back as he physically stands behind yours?

"Behind" is defined like this: If one friend were to move towards the other friend, he would at some point touch the other friend's back.

(For the record, I did leave a "loophole" answer.)

The sun would count as a light. So would a UFO beam, car headlights, etc. etc. etc.
