When I was about five or six, I noticed that when one person would yawn, the person next to them would yawn, then another person, etc. This was an interesting phenomenon that I was sure I could puzzle out. Well, I knew that there were these "invisible" latitude and longitude lines surrounding the earth, and I knew that the earth spun. So I figured that whenever you passed under one of the lines, you would yawn. Then the next person would pass under and they'd yawn, etc.
