Dada of NFTs, the future is going to call this Cleese’s bridge for NFTs as we call Duchamp’s urinal. It will probably sell, that’s why he didn’t just tell us the joke but also listed it.
I don't really see the downside (oh yeah, planet's burning, but as the dog in the cartoon said, this is fine), if some rich jerkoffs buy it then Cleese can put the money into charity. I suppose one downside is that the NFT ponzi peddlers can now say "See, we're legitimate, even the founder of Monty Python is here!", but Cleese's comments about terminal insanity isn't exactly support.
I suppose everyone knows the emperors are naked, but hey, it seems like that's not stopping megabucks being made, and why should you miss out?
NFTs have already started mocking themselves, almost as soon as any money has been spent on it (for example banksy's "I can't belive you morons actually buy this shit: https://opensea.io/assets/0xdfef5ac9745d24db881fef3937eab1d2... selling for $350k). This is just another high-profile example (though I think it's a slightly pointier critique at NFTs).
