A bunch of Dan Schneider people made appearances on this show. Jennette McCurdy was Dustin's girlfriend in one episode (who seems to be a Spiritual Successor to Sam) , Miranda Cosgrove was a science prodigy in another, Daniella Monet was Chase's girlfriend in a couple of episodes, and Allison Scagliotti (Mindy on Drake & Josh) was the girl who stole Zoey's backpack idea in one episode.
In "Silver Hammer Society", one of the Silver Hammers would later be Zeke Beakerman.
In "Zoey's Ribs", the imposter Pierre Le Mange is Loren Lester, better known as the voice of Nightwing on Batman The Animated Series and Barbeque on G.I. Joe.
