I got this game from a funny (IMHO) BBC panel gameshow "Mock The Week."
Here's how it works:
I give a scenario for an event which is almost certain never to happen, and you give your suggestions to the scenario if it were to happen. There is not really any competition except to make it funny. The only rule is so that same suggestion is not used over and over is that you come up with 10 suggestions, being 1 poster with 1 suggestion, and then the 10th poster with their 10th/last suggestion comes up with a new one. That is if this gets that far.
An Example
If I were to say "Exam Questions", then you would suggest Exam Questions that would never ever be suggested or used.
Like: "Old PE teachers are paedophiles, discuss."
I got this example of the game show itself.
I'll start:
I'll start with another example of the show that's a good one. And I'll put a suggestion of the shows.
"Commercials that never made it to air"
"Accident at work? Look where you're going you dosey bastard!"
