Episode Guide

#Twinfection is the 18th episode of the first season of Sam & Cat. It aired on November 16, 2013.


When Cat attempts a magic trick on Sam, and fails, Sam comes to the conclusion that Cat is not as smart as she. Determined to outsmart her roommate, Cat finds two twin boys at Bots and asks their mom if she can babysit them. The elaborate scheme Cat and the twins pull off to trick Sam works, and Cat celebrates her victory in song. Sam seeks revenge by getting her twin sister Melanie (Jennette McCurdy, reprising a dual role from the iCarly episode "iTwins") out to Los Angeles from her boarding school in Vermont, then making up an illness known as "twinfection". The two devise a plan using the "twinfection" premise, and play a trick on Cat.
