"JACK IS DEAD" spelled backwards for one. Also "ENOHP MUN"...... maybe it will tie in to next season.
Couldn't resist. LOL. I called the number. It's the "Nextel phone for 24".
Or
PHONE NUM whoa!
Edgar was trying to tell Chole to give up her dreams of Jack and to call him.
How sad :(
Perhaps next season they will meet in CTU Heaven with Teri and George and Sherry and David and Michelle and Tony and Chappelle softly humming Blue Eyes Crying In The Rain in the background as they embrace.
We'll find out next year, hehehe.
