~*~THE OFFICIAL TOPIC SERIES~*~
These things run 24 hours for 24-hour matches.
The rules are of course, to come up with a humorous reason as to why the loser of the most recent contest match lost, or to second someone else's reason. Reasons have to be original, so reasons that have won in previous contests aren't eligible.
