You might (or might not) want to put aside a bit of time and explore the records of The SCP Foundation.
If you're looking to review examples of the SCP Series (as well you should), you might start here (moving up the object classes):
SCP-085 "Cassy" (Safe)
SCP-294 The Coffee Machine (Euclid)
SCP-231 Special Personnel Requirements (Keter)
This last one, the source of the post title, should be accessed with extreme caution only after [DATA EXPUNGED].
