Ouch! Maybe some road-raging motorists need the Zen Antidote: Motorist bites cyclist's ear off! A motorist in Germany passed two cyclists very closely, although the entire roadway was clear. One of the cyclists waved his arm in protest (*ahem*), so Mr. Uptight Motorist stopped, jumped out, assaulted the cyclist and bit his ear off.
