I have a tendency to over-analyze things, including the titles of things.
1) Was there a Monkey Ball before Super Monkey Ball?
2) If they got rid of the panelist interviews on Jeopardy, they wouldn't run out of time as often
3) Why didn't Canada buy Alaska?
4) There might be things which exist that cannot be seen, felt, tasted, heard, or smelled.
Boy, am I weird.
I thought observation number 4 four above was most probable, as I think of, for example,
other dimensions not yet discovered. I would offer that there may be advanced highly
intelligent beings resident in other dimensions, "doors" to which we may not currently be
able to enter. I would offer this as "food for further thought".
