Here's an interesting example: in the Whoniverse there is this concept of a "deadlock seal", which is kind of a lock which is almost impossible to break (it is (in)famously resistant even to sonic devices, which is a big deal).

I can only assume this is a deliberate joke of the authors, of course.
