Response of a library co-worker, to my new joke.

My new joke I was telling all the (undergraduate) students at my library job like a month ago, was, I'd set them up by saying that I was going to tell them a life lesson, and then I'd be like, "Remember, always shit on the clock."

Like the third student I told that to was a sophomore, and he was like, "Of course!".

Then, he was like, "That's 101."
