My favorite is sitting at a light and have some clown in a riced out heap standing on the gas making that crazy gazoo noise.....just dying for some attention.
I can't help but laugh and think about how, when I was a kid, my friends and I would clothes pin a piece of cardboard to on the frame of our bicycles so it would slap against the spokes as we rode....make some noise...feel like we were going FAST.
