CarlyC Sam and Freddie think it will be good for their show if it is critiqued; Carly insults an 11-year-old critic, and is worried he will give a bad review.

Nevel Papperman is back, and instead of trashing iCarly in his articles, he has directly sabotaged the website itself. Meanwhile Spencer persuades the Plain White T's to perform on Carly's show as a favor for preventing lead singer Tom Higgenson from being hit by a falling sign at the mall. But how do they expect the band to perform on a show nobody can see?

Paying homage to "It's a Wonderful Life" and "The Twilight Zone Person or Persons Unknown," and lifting dialogue from "A Charlie Brown Christmas," when Spencer builds a metal Christmas tree containing an electromagnet that sets the gifts that Carly plans to give on fire, she wishes that her brother had been normal. An angel named Mitch hears her wish and grants it, which teaches her a valuable lesson.

To make matters worse, after struggling to negotiate the return of the rights to her website, Mandy ends up being tricked into signing it over to Carly's nemesis, Nevel Papperman. Now Carly and her friends must do all they can to take it back from Nevel, who's willing to give it back to her... in exchange for a kiss.

Carly and martial-arts champ Shelby Marx (Zoey 101's and Spectacular!'s Victoria Justice) agree to have an exhibition fight for charity after Carly jokingly challenges her to a match. Unfortunately, Carly accidentally falls on Shelby's grandmother during a press conference. Thinking Shelby wants revenge, Carly backs out of the fight, only to be ridiculed as a coward. Carly visits Shelby and apologizes, and the fight is back on. However, Nevel Papperman alters a clip of the press conference to make it look like Carly intentionally tackled Shelby's grandma to dupe Shelby into fighting Carly. Shelby, furious, attacks Carly for real during the match, Carly then holds Shelby's leg for the rest of the "fight".

The cast introduces various bloopers and outtakes from the entire series.

An online video of Nevel Papperman verbally abusing a little girl in a supermarket makes him one of the most hated kids in the world. With nowhere else to turn he attempts to seek help to restore his reputation from the most unlikely source... his sworn enemies, Carly Shay and her friends!
