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
Dude over there! If you're clueless about what's going on I'll keep it brief. We're at a jail in which we're outside and attacking the guards until a zombie apocalypse happen. Now somebody just found a helicopter and we're using it to escape.
Eat lead, zombies! *shoots at zombies* um, i still have some wax left over to seal off toms legs like i did with whatshisface. *uses wax* we should take off now, before the stealth plane warms up.
me? what do you mean? i didn't blow it up the zombies did. and besides, there is the other stealth plane on the other side of the complex. tom is a zombie now, somewhat. NOT A GOOD SIGN. here, have some brains. *scoops up some brains from the ground and throws them at him*
