When I was a senior in high school, our Chemistry teacher wore suspenders everyday. Someone started a fad with us kids in his class wearing suspenders on Fridays. I saw all kinds of suspenders. Disney, Warner Brothers and other types of cartoon suspenders and also plain colors. I remember the one girl in our class wore hot pink suspenders. I wore plain black.
The teacher took it pretty good. He kind of kidded us about it and then on Thursdays, he always reminded us to wear our suspenders tomorrow (Friday). During our last week of school, a couple of the girls made him a cake that resembled a suspender. He loved it.
