Janice's apartment building is called "Feeney Villas" and Sylvia's is "DeFazio Apartments". Feeney and DeFazio are Shirley's and Laverne's surnames on Laverne & Shirley respectively.
When Sam and Cat watch "That's a Drag" they notice the characters using a Banana Computer "because you can't show a real Pear Computer on TV."
Of course, the Pear Computer is a running joke on all of Dan Schneider's shows. The process of hiding a real trademark of a product on a show is called "Greeking." The idea of Greeking is to avoid the use of a real trademark for any reason. Although in some shows, the Greeking is done in hopes that the viewer does not notice, the running gag in Schneider's shows is how blatant and obvious the greeking is!
According to the show's creator, Dan Schneider, "Sam & Cat" is the first show ever to be a spin-off of two different shows.
Even though Sam and Cat both appeared in the episode "iParty with Victorious" Cat only recognizes Sam from "iCarly" and Sam does not remember Cat at all. According to Schneider, "they never really interacted [in iParty]. So, to me, this is their first real meeting – and I love that it happens in a moving garbage truck."
