CHINESE FIREDRILL
An ol skoo game that you play while driving.  Your car needs to be full of people.  When you stop at a red light, you put the car in park then ALL passengers (driver included) get out of the car and quickly switch into random positions elsewhere inside the viehicle.  The object is to pull this off before the light turns green...Otherwise you're screwed.
It is fun when the passengers are caught off guard and the driver suddenly cries out "CHINESE FIREDRILL!!!" and everyone is hella frantic.  

The modified version of this is to do CHINESE FIREDRILL with multiple cars following back-to-back each other, as in Joshiro007's birthday.  Every red light or stop sign encountered, triggered everyone to get out of the cars they were in and either go in another area of the car or a totally different car altogether and resume driving.
