I have an idea for a supervillain: an insane deity that wants to completely control all of, as he puts it, "the:
- Who
- What
- How
- Why
- Where
- When
and
- Whulk
...of:
- Thought
- Matter
- Energy
- Force
- Space
- Time
and
- Shmungo."
There will be a running gag where someone asks him "...Shmungo?" to which he replies "Yes. That one's especially important!"
Beyond this, "shmungo" will never be explained.
