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?
