During prohibition era, there was a brick of dried grapes being sold as a nutrition supplement or something like that, but it had a “warning” sticker attached saying specifically not to dissolve it in a specific quantity of water, and if that were to happen, do not let a specific quantity of yeast to fall in it, and especially not to let it sit for 6 weeks, or else you might end up with wine, which is forbidden!

I can see a cheeky sort of company selling a phone with a little warning label attached to it…
