To those who've been wondering if Scotty is a masochist and why he remains in his job: Today the myster has been solved. In his press briefing, Scotty repeatedly alluded to the fact that he has "lost a piece of flesh, you just can't see it yet". Apparently, Scotty has stumbled on a positive side-effect of being pummelled with questions he can't answer.
Unbeknownst to himself until today, Scotty has stumbled into a brilliant weight loss method. As many of your honest folks out there probably don't realize, repeating pointless platitudes with a straight face a few dozen times requires a concerted effort of every muscle in your body. Thus resulting in a weight loss of 2-3 pounds (equivalent to a "piece of flesh") every day this weight loss program is applied.
Since Scotty has about 20-30 pounds to untill press will notice, the half life of his job is most likely two weeks. Ten working days at 2-3 pounds a day and he'll be in fighting shape.
