CBS.com considers this to be the 199th episode, and "Home Cheapo" to be the 200th, because they consider the two-part third season finale, "Pregnant Pause", to be one episode.
The German episode title is "Wer schön sein will...", meaning "Who Wants to be Beautiful?"
This episode, where Spence sings a 'subway safety song' that warns against such perils as standing too close to the edge of the platform, aired the same day a news story broke about an epileptic falling onto the tracks as an MTA subway approached, and then being saved by a quick-thinking commuter who dove in after him and pinned him in a drainage ditch as the subway passed over top of them.
Doug's description of commands he's giving to his Nintendo DS are those one would use when playing Nintendogs.
The montage of Spence helping take care of the Palmers mimics the opening credits to, and uses the theme song from, Mr. Belvedere.
Arthur calls Spence "the hobbit," comparing his short stature to the diminuitive race created by J.R.R. Tolkien for his 1937 novel The Hobbit.
In the cold open, Doug refers to a guy at the car wash as "Mr. Spacely," comparing him to George Jetson's boss on The Jetsons.
