Dress up like a clown and time your rides so that you'll encounter the bus. Stay behind the bus and stop right behind it when it stops to let the brats off. Make faces at the kids in the bus when it's stopped. After a few stops, when the bus is stopped, pull up right alongside the driver and make weird faces, hand motions, etc. to him/her. The bus will floor it to the nearest purple triangle safe space, and the driver will probably have to undergo trauma counseling .
Or, is the collective attention-span of the masses so short now that nobody remembers the creepy clown media hoax hoopla now?
