What are the most interesting examples you've seen of cast usage?

Ha I think I've seen this one before. Love it!

We used (abused) it here: https://github.com/memester-xyz/surl/blob/034c912ae9b5e707a5afd21f145b452ad8e800df/src/Surl.sol#L91

Its a pretty basic use case, but using cast to debug failed transactions does wonders.
cast run {TX_HASH}

Can be used to extend (read: hack) forge scripts when functionality isn't exposed or doesn't make sense as a cheat code.

An example is signing something with a hardware wallet.

I run the following multiple times a day

cast block --rpc-url "$NODE_URL" | grep 'timestamp\|number'

copying storage from one immutable contract to its new version.
(have not seen but imagine possible as part of a script with json file storage maybe... ?)
