My friend Greg and I printed up a bunch of surreal or self-contradictory cards and objects back in high school (e.g. a bookmark that said “This is not a bookmark”). I just came across this at the bottom of a box of printing stuff. I don’t remember doing it, but given the content and the very un-professional inking, it looks like something Greg and I did in that era.
