The game is very similar to this except it's impossible to do it all in 90 seconds here.
Rules are simple: starting person makes a scenario and starts a sentence with a letter. The next person starts another sentence with the next letter, the person after that does the same and so on. When we eventually reach the starting letter, the person who hit that letter creates a new scenario, picks a new letter, and it starts over.
Example: (starting letter = B, scenario = the office building's on fire) Person 1: "Bring me this month's financial reports." Person 2: "Can't you see the building's on fire?" Person 3: "Does it matter?" Person 4: "Everyone else is evacuating."
Ok now it starts Scenario = You're on the Titanic when it crashes into the iceberg; Starting letter = J
Aha! I think we should round them up and bomb the evil homicidal robotic 'eople' who are part of one of the world's most peace loving religions and are unable to kill us so that we can use their bombs on them!
Just hold on a second what if we have the prates fight the robots, ever watch spongebob? The pirates beat the robots in pirate robot island so why not here too?
