What are some weird corners of the internet you've stumbled across?

I don't mean gross stuff like SomethingAweful.

I'm talking someone's fever dream neocities page that details how to make a UFO engine using element 115.

A blog that is wild conspiracy stuff that has aged like fine wine.

Or some serial forum post that makes no sense but seems too complex to be performative.

17776 is a good example, if you're not familiar.
