When I was a kid we used to take a lot of road trips, and when we got stuck in traffic my mom would always say, "look at this traffic jam." I was about 4 or 5 and I would look at the window for "traffic jam" but didn't know what she was talking about. Then, while playing outside, I saw some puddles in the street with oil floating in them, and I came to the conclusion that this was "traffic jam". I told this matter-of-factly to all my friends in elementary school, until my older sister made fun of me for it.
