The world’s most expensive banana has been sold at an auction for more than $6 million. It’s Maurizio Cattelan's 2019 work Comedian and it’s literally just a banana duct-taped to a wall.

The new owner bought the right to display the installation along with a guide on how to replace the fruit (it doesn’t stay fresh for long!).

But what makes it art? And why would someone eat a multi-million dollar banana?
