Passcode Hack?

Rhett,
Just noticed that at 5:17 into the 200 year old person episode (Aug 8, 2012) you entered 6884 on your I pad, am I right? Since I may live well beyond retirement age I might want to adopt password hacking as my golden years hobby.  My wife and three girls thoroughly enjoy your show (myself included) and thank you for educating, entertaining, and challenging the Mythical Beasts in all of us!
