I used to think that the wind chill factor was the windshield factor. I surmised that there there was an official speed (like 50mph) at which they measured the temperature of the windshield. I feel less crazy after reading other peoples’ childhood beliefs and amusing memories.

On a slightly related note, misheard lyrics can be amusing, especially when you’re singing them out loud with the intent to be romantic and your date bursts out laughing.
