There was a Star Trek:TNG episode where Dr. Moriarty (of Sherlock Holmes books) was created in the holodeck and had enough intelligence to take over the ship from the holodeck, and when trying to leave the holodeck was actually transported into another holodeck, but really this holodeck was in a cube that could sit on your desk, and inside it, Moriarty thought he was outside of the Enterprise holodeck and out exploring space, when he was really in this cube on Barclay's desk, and anyway..... That's a really long sentence.
Ever read 'Horton hears a Who?'
I once got into a discussion with someone who thought that our universe was actually just a ball of snot inside another universe, and that was just a ball of snot inside of another universe, and so on.... gross, I know, and rather retarded. I'm going now.
