Betty White will guest-star on the season finale of The Middle. The four-time Emmy winner <a href="http://tvwatch.people.com/2010/03/12/betty-white-to-guest-star-on-the-middle/2">will play a school librarian</a> who goes after a student over several overdue library books.
What? A librarian chasing down an overdue library book? What hijinx! Oh, one can only wonder where these writers get their ideas. We can only hope that zaniness and uncontrolled hilarity ensues.
