What's the difference between a drunk driver and a stoned driver at a stop sign?
The drunk blasts through it at 80 mph and smashes into a mini-van, killing all 6 kids inside.
The stoned driver sits at the stop sign for half an hour waiting for it to turn green...
unless its a 4 lane, the stoned driver puts it in reverse and slowly backs up, the car in the adjacent lane thinks there moving forward, freaks and slams on the brakes.
