what to do in the car?

Portable dvd player and a few dvds.

um...fornicate?

drive, A-B, go places, go threw drive threws, long journeys, listen to music, park and have S**, have a crash, get chased by the police, run over old Lady's, eye spy, yellow car, hit n run, chicken, killer horn, wake up, and excellent place to put a body, in the trunk.

Depends where youre parked - whoops sorry! buy a double DVD player from Argos so that you can sit in the back with a friend and watch the same film with a screen each.
Look to see how many foreign number plates you see during your journey.
Make up words from number plates i.e.
BNO could be Bowels Not Opened
FNY = funny or fishing in New York
SRB = sorbet
its surprising what funny ones you can come up with.

punch bug no punch back, i spy, are we there yet?,dvd movies psp

20 questions, I spy, noughts and crosses if there is condensation on the windows, name an animals, fruit etc in order beginning which each letter of the alphabet.

depends on where you are driving???
when we are in wale's we play a game called bath's as they are all over the place, 5 points for spotting one and 10 if it is in an obscure place as they some times are.
or when we are going through suffolk/norfolk we play horse's, same kinda thing you get 5 points for a horse and ten for a horse box.
the only rule is its thefirst person to shout it!!!!
in essex do the same for a chav 5points for the sterotype and ten for the young mum with the buggy.
good luck and i hope you enjoy we get endless fun!!!!
