In the scene when Carly and Sam are caught texting with their PearPhones, they were holding black, but in the scene change it was blue (same as Victorious Updates).
In one scene, Robbie/Rex spill a drink causing the music to stop and so a rap-off starts. A few minutes later in another scene, Andre is still trying to find the panda bear and everyone is dancing to music. Shortly after that, the rap-off is still going on.
When Freddie goes to find more pics of Tori, he finds a picture of her performance from the episode Beggin' on Your Knees. Beggin' on Your Knees had not occurred yet since Jade's hair is still brown and this was filmed shortly after the first season, before Jade's hair was dyed black.
In the background in the scene where Andre tells his grandmother to go home and when Carly calls Freddie, you hear Jade and Cat singing "Give it Up." This is from Victorious episode "Freak the Freak Out." In Freak the Freak Out, Jade and Cat probably didn't record themselves singing the song and they couldn't have been performing live because Jade was in the jacuzzi with Spencer, Sikowitz, and Beck and Cat couldn't speak because of her throat growths.
In the scene where Trina gives Cat the two little kids, in the background you can here the song "Give it Up", however in a previous scene, Robbie broke the sound system.
Unless Sam raided Kenan Thompson's refrigerator for cold butter (which has not been determined - though most likely not, because Kenan had not yet moved in), her butter sock would otherwise be rendered useless because it would have melted by the time she retrieved it from her backpack.
After the iCarly gang arrives at Monie's house to get their disguises, there is a brief shot of the sun setting and the "Hollywood" sign - but the sun is setting in the wrong direction. A setting sun should travel through the frame from top left to bottom right.
When DJ Mustang played the theme to Leave It All To Me he said that everybody knows it. However, it is not known how, due to the fact that the credits of iCarly are the only thing that start with the song on the actual show and whilst the viewers in real-life know it, it is unknown to the Danwarp universe.
At midnight when they confronted Steven, iCarly.com was broadcasting it live but however since it was midnight no one would be awake to watch it.
Sam notices that Tori and Shelby Marx share a resemblance because both characters were both played by Victoria Justice, but no one notices that André looks like Harper, despite both characters being played by Leon Thomas III, or that Trina looks like one of the girls who attended Nora's party in iPsycho, despite the fact they were both played by Daniella Monet.
Carly and Tori say together that Steven said they were "one of a kind, just like you," although Steven never said the word "just."
Sam said that Mrs. Benson hasn't had a boyfriend "since Seinfeld got cancelled" (the date of cancellation was May 14, 1998); however she dated Lewbert in iHurt Lewbert, the original date of airing being October 18, 2008, well after the Seinfeld cancellation (of course, Sam could have been exaggerating).
Sam said that a long time ago she learned never to admit anything but in iOMG she admitted that she likes ham.
