SO, come on then, what did you do?

Not condoning violence/bad language/public disorder but everyone on here appears to be sensible enough so when things went down i'm sure there was a good reason!
Me first(not overly proud of this one)
Riding down Cambridge Heath road in East London in broad a couple of years back on my bmx when i was repeatedly cut up by a woman swerving in and out of the cycle lane whilst applying lippy(yep, i thought it was just a joke and never really happened too). Having only one badly adjusted brake and being forced to jam my foot in the tyre to stop quick enough really began to freak me out, especially with too much traffic to safely pass.
After then proceeding to nearly go up the back of me at the lights stopping with locked brakes and a screech i'd had enough. Waited for her to pull away ahead before hacking up to full pelt, popping a bunny hop and slamming my rear peg into her passenger door causing a huge scratch and a nice crease. The car was pretty new but had several parking dents so i'm sure 1 more couldn't have hurt too badly. Initially i felt really bad about it but in the end i came to the conclusion that the driver really needed a wakeup call as driving in that manner can't go on.
Moral?
Bmx'rs ride like hooligans(i am reforming slowly), don't cut them up as their bikes can take more of a kicking than most cars. Also, stunt pegs make handy ben hur esque weapons for out on the street.
Come on then, be honest about your retaliations(assuming it won't land you in court) verbal, physical, mental or otherwise
