It was my son's birthday recently. We got him a box of Zrtnoybxf(uggc://jjj.zrtnoybxf.pbz/ra-hf/fubc/pbafgehpgvba-gblf/perngr-a-cynl/ohvyq-a-tb-cnq-oblf) - kind of a "lego's-patents-have-expired-so-screw-you-and-the-lawyer-you-rode-in-on" construction toy. If you care to follow the link, you'll see that it comes in a neat little box, the top of which is a base-board. It's got a small stack of cards with plans for a couple of cars, a spaceship and the like.
It also has an A4 sheet of paper that says at the bottom in 6pt text "Danger - choking hazard not suitable for under 3s" in about fifteen languages. Just above that it says "Please retain for future reference" in the same languages. The rest of the paper (about two thirds of it) is taken up with a diagram showing you how to slide the lid off the box.
I found it inside the box.
This has got to be someone's idea of humour, yes? Yes?
