Viewers to Control iCarly Marathon on Dec. 5 By Casting Their Votes for Favorite Episodes at Nick.com, Beginning Nov. 28

Say it ain't so! A rift between iCarly BFFs' Carly Shay (Miranda Cosgrove) and Sam Puckett (Jennette McCurdy) puts their friendship to the test and takes its toll on their popular web show in "iQuit iCarly," an original Nickelodeon movie, based on the hit series, premiering Saturday, Dec. 5, at 8:00 p.m. (ET/PT). The programming event will kick-off at 5:00 p.m. (ET/PT) with an iCarly marathon - as chosen by the viewers in an online poll - chronicling some of the most hilarious situations the best friends have encountered together.

In "iQuit iCarly," the iCarly gang invites two up-and-coming wacky web comedians, Fleck and Dave, to be guests on their show. When Carly and Sam learn that the guys are entering a web contest for a cash prize, they volunteer to help create an awesome video. Unfortunately, Fleck and Dave have a big blowout which results in Carly and Sam taking sides and putting their own friendship to the test. Their rift makes it increasingly difficult for them to continue doing the web show, leaving Freddie and the rest of their fans to wonder if this is the end of iCarly. Meanwhile, Spencer's obsession to win a boat pays off and he finds himself the owner of a new speedboat. However, without a place to dock his prize, Spencer is left to captain the boat in the parking lot, much to the dismay of one of his neighbors, who plays for his college's baseball team - the Pirates.
