The peeing by the side of the road is right on. I remember driving in Nagano about a year or two ago and there was a group of tour buses and their inmates in a small parking lot just really pulled off the road. This guy obviously really needed to go, and felt that he should turn away from the group out of politeness. Only one flaw with his plan - he ended up peeing into the oncoming traffic. Gave us ashock as we came round the corner....
