"4. If the challenge posted is old, you may say so unless someone else has already, a topic with 20 people saying "old" does no one any good, please include in which movie it was done and who did it... maybe a link as well.
All the "old" posts after the first one of these will be removed without warning."
The same rule should apply to saying "impossible". I mean what the fuck, if you saw a couple of guys say it ain't gonna happen or that it's impossible, you don't want to be the fucknut who's gonna keep the line going.
