Helen Klench (voiced by Cheri Oteri) is the grumpy librarian who is often mistaken for objects such as brooms or toilet brushes. The pills found on the pilot appear to be hers and turn out to be female hormones. His catchphrase is “Quiet down!” and seems to have a love-hate relationship with the bisexual drama teacher Andrew LeGustambos. She is a staunch advocate of the library, because as she puts it, "Where else can you find dated and limited amounts of information if the Internet goes down?" Helen Klench is one of the characters in the Fox animated series Sit Down, Shut Up, based on a short-lived Australian sitcom of the same name. It revolves around a group of “ambivalent if not just plain crazy” faculty at a small town high school in Knob Haven, Flrida. The show is part of the network’s animation lineup that includes The Simpsons, Family Guy, and American Dad.
