At one time or another, you've probably seen this image. It's an iconic painting by the Belgian surrealist René Magritte. It's title proper is "La trahison des images" aka "The Treachery of Images" aka "Ceci n'est pas une pipe" aka "This is not a pipe". Magritte says:
"The famous pipe. How people reproached me for it! And yet, could you stuff my pipe? No, it's just a representation, is it not? So if I had written on my picture "This is a pipe," I'd have been lying!"
Indeed it is very famous. So famous that there's probably a million different parodies of it in one form or another or another or not another no not. There's simply too many variants to go into here, a multiverse of "this is not a (insert any object here)" and we won't delve those deep murky depths. Instead we'll stay relatively on topic with a short survey which mostly retains actual pipe content. Some are clever, some are funny, some are dumb and some take themselves too seriously, but whatever...
