Homer and Bart watch this show on TV
Maude says, "Remember those scary lepers in 'Ben-Hur'?"
When Homer & Bart think they have leprosy and try to get into the Flanders' house, they start clawing through the letter box and shouting "Brains!" because the "leprosy" makes them look like zombies. The scene is also filmed much like the 3rd act of this movie.
Bart asks if he and Homer can get "a room with a view".
The Virtual Doctor Web site comes "from the makers of 'Dragon Quest.'"
4 clips of Homer injuring himself play when they talk about Homer getting addicted to painkillers, this is one of the episodes the clips are taken from.
