Trivia: At the end of the episode when Betty White is asking for donations, you can see characters from many other Fox shows manning the phone lines: Bender the robot from Futurama, Hank Hill from King of the Hill, Thurgood Stubbs from The PJ's, Mulder from X-Files, and Luke Perry from Beverly Hills 90210. The owner of Fox, Rupert Murdoch,is also answering phones. The logo from Family Guy is also on the TV Betty White turns off.
Trivia: In this episode the Simpsons are labeled finally as a "northern Kentucky family"; this was quickly enough dismissed as a red herring for various reasons. To further mystify, however, if you turn on the English subtitles on the episode, they say "southern Missouri family".
