I was a few minutes early to class.
The teacher was doing paperwork. There were two girls singing to pass the time until class started. They finished one song and ask if there were any requests.
I’d like to request the Sound of Silence.
The girls didn’t realize I was being a smart-aleck so they actually started singing the Sound of Silence.
After a few seconds the teacher got the joke, looked up at me and grinned.
The girls never did get it.
