Several Drake & Josh actors guest-starred on Victorious over the years, such as Drake Bell, Jerry Trainor, and Yvette Nicole Brown, but there was one actor who had a regular role on the show that you probably didn't even know about. Jake Farrow voiced Rex, the sassy-AF puppet — or Christopher Cane, if you're going by the "Blooptorious" episode — but before that, he played everyone's favorite weirdo Premiere employee, Gavin.
Since most stars on Dan Schneider's series tend to guest-star on other shows in his canon, this normally wouldn't be that surprising. However, Farrow's Rex voice sounds nothing like Gavin's voice, which makes it that much harder to tell it is him if you're not looking at IMDb.
Actually, Farrow is a huge part of Schneider's world: Besides acting on the shows, he's also written and produced a ton of episodes for iCarly, Victorious, Sam & Cat, Henry Danger, and Game Shakers. The latter two are still currently on the air on Nickelodeon.
Of course, Rex and Gavin share similarities, if you think about it. Both don't like being told what to do and outright ignore whoever's speaking to them (hi, Josh Nichols and Robbie Shapiro). Not to mention they each tell it like it is and don't hold back. And honestly, that's just how they should be.
