Tenth Grade Puns

It was the end of class. Before dismissing us, he informs us that we won't be having class the next day and will instead be going to the gymnasium for an assembly. When the bell rang, as everyone was leaving class, I went to his desk and asked what the assembly was supposed to be about. His Response:

"I'm just a mushroom." ...awkward pause, stare... "I live in the dark and people drop crap on me."

I wasn't really sure how to react to that. With a confused look on my face, I just turned around and walked out the door. I'm still not sure if that was a dad joke or the musings of a bitter old man. Maybe both. I don't know, it just seems like it belongs here, if only for the sheer awkwardness of it.
