I was in a car when the kid in the passenger seat was yelling at pretty much everyone we drove by. It was pretty memorable to say the least. One guy stopped mid-jog and turned around after us, I'm in the back seat thinking "please don't break down, wtf"!
Back when I had really long hair I used to get the word "HAIRCUT" shouted at me a lot from passing cars.
I only tend to do that every third Sunday. Too often makes it a pattern and I do try to have it coincide with when I have finally had a bath.
