I thought that teachers were assigned to certain grades based upon how smart they were, i.e., the ones who taught first grade were the least intellligent, the 2nd grade teachers were a bit smarter than the first grade teachers, and the 4th grade teachers must be the smartest teachers of them all. Then I told my 2nd grade teacher a really big vocabulary word ("entomologist") that my 1st grade teacher had taught me the year before, and when my 2nd grade teacher truly didn't know what it meant, it blew my mind.
