I reckon it's about time for a new game:
What about something like this - You come up with a car name (make or model) and the next person has to come up with one that starts with the letter that the other one finished with. (eg. GMC , Chrysler, Rover etc).
I know it's pretty lame, but it's the best I could come up with off the top of my head. Feel free to suggest changes. No duplicates if we can, and no names that end in numbers (eg RX-7).
Here we go (*fingers crossed*):
You can only be young once. But you can always be immature.
