I once took a ciggarette butt to the throat at 70*cough*mph after some twonk flicked it out of their window as I passed them. Que frantic beeping and waving at their front tyre and making "pull over" actions. I pulled over with them and when they stopped, farly ashen faced I dramatically said "Your tyre is coming apart!!" Bloke scrambles out of the car to look, and as he looks back at me after checking out his perfect tyre, I said sweetly "Oh, must have just been that fag you chucked at me. Nevermind."
Neeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaawwww!!!!!! As I rejoin full speed traffic in about 5 seconds, leaving him to find a gap in the heavy traffic that his Vauxdull Fronterra (acceleration about as good as a fully loaded artic) could speed up into.
EDIT: On reflection I wished that I hadn't told him about the fag, and just left him to feel nervous!
Never had it en velo
