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
Darn you! You know tis bad luck to speak on the maidens of the ocean! They say just a look is powerful enough to set a sailors mind upside-down and send him to the deep of his own volition. So no. We shall not.
Ger, would somebody throw him in the brig, we're on the ship, in the middle of the ocean, we left that isle a while ago. You can still go see the maidens but you will be on your own in the row boat. Is that The Isle?
