Mr. Garrison: Second star to the right, then straight on 'till morning.
Mr. Garrison says this at the end of this episode when he's asked where to go by the bus driver. This is the same line spoken in J.M. Barrie's 1904 play "Peter Pan."
This line, or variations of it, have been spoken in a number of subsequent productions, such as by Captain Kirk in 1991's Star Trek VI: The Undiscovered Country a film bounding with literary references. In fact, Mr. Garrison's use of the line most closely resembles Captain Kirk's; Kirk said it when he was asked where to navigate the Enterprise, much like how Garrison was asked where to take the bus. It even has the bus disappearing into the horizon leaving only a shining "star" light thing just like in Star Trek VI, though in Star Trek VI the Enterprise was covered in the light of a nearby star.
