This is the first episode to feature Eric's famous Feeny Call.
Although Eric appears in the MTV dating show Singled Out, the co-host Jenny McCarthy was not featured for unexplained reasons.
In Cory's sedative dream, Shawn mentions that Cory slipped in to the 4th dimension commonly known as the Bottle City of Kandor. This is a reference to the Superman comics. The Bottle City of Kandor is a city from Krypton (Superman's home planet) that was shrunk by one of Superman's enemies, Braniac, and put into a bottle for his collection.
