I remember in maybe middle school a teacher giving everyone in the class a piece of paper with a massive list of instructions.
They were silly things like “sing the first Ceres of your favorite song” or “do 10 jumping jacks.”
But the first instruction was “read all the instructions first before doing anything listed here.”
The last instruction being, “ignore all of the above and hand in your paper.”
About 3/4 of the class ignored the first instructions and went through all the silly stuff. Was pretty funny.
