When I was a little kid, I thought that traffic lights were controlled by toucans (like Toucan Sam from Froot Loops). I thought that there was a toucan in each and every traffic light and that there was a candle set behind each color of the lights; red, yellow and green. So, the toucan would light the appropriate candle and blow out the other candle when the time came.
And those flashing lights... Or when a traffic light was broken and just the red light or just the yellow light would be flashing... Well, I thought that was because an evil Keebler Elf had made his way into the traffic light and was repeatedly blowing out the toucan's candles.
