From Lostpedia:
A poster for the fictional band Dirt Spigot can be seen in the room Miles works in. In the episode "Fire + Water", the director of the Butties Diapers commercial says that he actually wanted Dirt Spigot for the ad instead of Drive Shaft.
-and for the star wars fans-
Tunisia was used by George Lucas as a location for filming the Tatooine scenes, and the musical cue when Charlotte arrives there is very similar to the "Binary Sunset" musical cue of John Williams' score for Star Wars Episode IV: A New Hope. More specifically, the town of Medenine was used as Anakin's home in "Star Wars Episode I: The Phantom Menace"
The scene where Charlotte is hanging upside down from her parachute trying to free herself is an homage to Star Wars Episode V: The Empire Strikes Back, where Luke attempts to free himself from the ice cave from which he hangs upside down.
