If this episode is anything like the last two, it'll be a natural disaster. Plus they've already parodied all the big hit shows to some extent: Lost, Desperate Housewives, Ugly Betty (even though it was an Ellen sketch), 24. Why can't they do a parody off of something clever like I don't know RENO 911 or SUPERNATURAL or something they haven't touched yet.
***Scratch that, I can't picture them pulling off a RENO 911 parody effectively given the season's status and quality as of right now.
