I'm sure a lot of people here are familiar with the "23 Enigma" as portrayed in the movie The Number 23 with Jim Carrey, and I also read about the "11:11" enigma that someone posted about here... are there any other number related enigmas out there?

I've been scouring the internet for anything related, but haven't been able to come up with anything. Any useful or interesting sites, or ideas, anyone?
