As a pun-lover, I have weighed in on this before. It may help to note that the topic of your first-grade controversy was "silly names for Superman". In this case, "Pooperman" is clearly the funnier name.

I thought it was pretty clear from the answers that "silly names for Superman" was the (unwritten) prompt.
