  • In the episode's trailer only Stan was shown to be aware of the fact he may be the source of the opium supplied to the entertainers like Chuck E. Cheese (there was no reference to other characters in it) while Kyle, Cartman and Kenny were depicted joyfully supporting Marcus Preston's chase after the drug dealer, however in the actual episode it was changed that all boys were shocked and knew what was going on.

  • Prominent students such as Heidi Turner, Jimmy Valmer, Token Black, Timmy Burch are nowhere to be seen in the opening Marcus Preston's birthday scenes.

  • The name of the Shady Acres' receptionist is revealed to be Vicky, while the two male nurses are Tony (Asian) and Toby (white).
  • In Marvin Marsh's room there are pictures seen in episodes such as Cash For Gold (featuring him and his now deceased Border Collie) and a full family photo, as seen in the Marsh Residence throughout the series.
