The really good thing about having back to back episodes is not having to wait a week for a story arc to play itself out. Mandy Moore gets the patented Scrubs Celebrity Fan Blower Treatment and between this and her guest arc on Entourage has proven herself to be a good sport about stuff like this.
Although they seem to be making J.D. goofier than normal this season even by Goofy J.D. Standards.
I think their hubris has caught up to them. They believe that whatever they put on the air will be comedy gold, even if it's only because they'll be laughing at the people who watch it. I have felt this coming since they switched to the cue cards.
