I had a guy throw pennies or some shit at me one time and then jump off the exit. This guy came up on me, I had done nothing. Two guys just being assholes. What they didn't know, is that I'd slam on my brakes, cut across the grass and onto the off ramp. What they also didn't know, is that I had 3 little glass vial stink bombs taped around a m-80 (or whatever, one of those fatty fireworks.) in my center console. So, a few moments into arguing back and forth driving along side each other, I lit the fucker and threw it in their car then quickly hit a uturn spot and was gone. Saw them hit the brakes and pull over further up. Sux for them.
I have another one of these contraptions, btw. However, it's in my garage and not my car.
