/r/SCP. It's the subreddit for a fictitious wiki that lists thousands of anomalous objects, all being contained by the SCP Foundation (Secure, Contain, Protect). They've got everything:
A vending machine that will produce any liquid you can name
Tomatoes that hurtle towards someone if they tell a bad pun
Monsters that are impossible to kill, and nearly impossible to contain
Eldritch horrors so powerful that even writing down their information could destroy the world
An object that nobody knows anything about: what it is, where it came from, when it arrived, and who wrote the document.
A green goo that improves anything it touches. Just don't put it on a dead body.
