I put notes on the printers one year for april fools that said they had recently had voice command modules installed. It was not well received but I thought it was hilarious.
One manager got MAD that the employer spent money on printer upgrades instead of staff. After her red faced tirade, when I was able to talk again after laughing very hard I explained to her that it was a joke. She still looked pretty mad.
I once ordered a sheet of small "for rectal use only" stickers, and put them on a bunch of things in the house like the our letter opener, my wife's leg shaver, a coffee spoon, and the TV remote.
Maximum hilarity for me, and lots of eye rolling from my wife.
Sadly as I am not the OG OP, I do not know. If you can find em, lmk, because I have been subsisting off of printed paper sheets and tape. Still quite entertaining :)
