Even though it was produced as the 399th episode, this episode aired as the "400th episode." As a special tribute, the opening montage was replaced with a black screen that reads, "20 Years Ago..." and the full showing of the Tracy Ullman Show short "Family Portrait", as a symbol of how far the series has come.
Lisa: One thing I've always wondered… How can Fox News be so conservative when the Fox Network keeps airing raunchy shows? They don't fit together.
(Lisa then proceeds to flips channels between Fox News and Fox Network until Kent Brockman takes the remote control away from her.)
Kent: Fox deliberately runs shows that will earn them huge fines which are then funneled through the F.C.C. straight to the Republican Party. Everybody in the media knows it, but no one has the guts to say it.
Homer: I'm sorry Marge, but I won't live under the same roof as a member of the liberal media!
Marge: You'll have to excuse him, he's been watching a lot of Fox News.
Homer: Did you know that every day Mexican gays sneak into this country and unplug our brain-dead ladies?
Homer: Hey suckers, check it out! Marge is taking me to ride dirt bikes at the cemetery.
Lisa: You're going to the dentist too, Dad.
Homer: (Thoughtfully) Why the cemetery? I wondered. But my dreams were too strong.
(At the dentist)
Homer: Aaaah! It hurts so much!
Dental Hygienist: I haven't even started yet!
Homer: I know, but a breeze from that window went in my mouth!
