What’s the weirdest thing you’ve ever done on Ethereum?

Everyone talks about trading, staking, DeFi farming… but Ethereum is a playground for everything. I once minted a pixel of my cat’s nose as an NFT and sold it for 0.04 ETH.

Let’s hear the strangest, most “why does this even exist” thing you’ve interacted with on chain.
