Someone made the claim on these boards waaaaay back (possibly old engine) that he got a kid that started on his D1 screen to sign at D3. As I recall, the explanation was that the kid had been 10 miles from campus, extremely low overall rating for the D1 screen, dropped the first day to D2 and gave the backup message when contacted by phone, at which point the guy pulled him down.
There were many skeptics when the story was posted and I'm certainly not saying it can be done (in fact, I'd be floored if it could), but the claim HAS been made that if the stars all align properly it is possible.
