Not super obscure, but I remember that one specific time when circular-linked-list made a lot of sense to use, well I wanted to use it so I used it.
I had a bunch of API keys with poor expiry documentation and implementation, so to find out if a key expired it had to be used. I put it in a main "keys.pop loop" and all methods below tried to use the key. If HTTP response was (some another obscure HTTP status code like) 505, I simply called `continue;` in the loop to jump to another, without caring at all where I was before.
