Episode list

Carly is sad when her father cannot escort her to a military dance; Sam and Spencer fix a motorcycle; Gibby gets his head stuck in an "artificial head machine" (because he sold his first one at the pawn shop); Freddie gets a new phone.

Carly gets a crush on Freddie because he saves her life and is injured himself in doing so. Freddie can finally have everything he ever wanted, but he is faced with a difficult question: Is this really the way he wanted Carly's affections?

When Brad and Freddie start hanging out, Sam wants to hang out with them too. After Freddie uses the app, it says that Sam is "in love." So Carly helps Freddie to hook Sam and Brad up. Meanwhile, Carly and Gibby do experiments on Spencer.

When Sam overhears Freddie admit he has never been kissed, she decides it would be fun to expose this confession on Carly's web show, until the rampant humiliation he receives at school makes her regret her decision.

Carly gives Sam a makeover when she develops a crush on a boy at school who only likes girly-girls. Somewhat similarly, Spencer thinks a girl only likes him because of a tuxedo.

Surprise, surprise! Sam has a twin sister named Melanie. Even more of a surprise, she's much girlier than Sam and quite fond of Freddie, who suspects that she's actually Sam in disguise. In the meantime, Carly offers to tutor a boy named Chuck, who has been a sworn enemy of Spencer, who struggles to convince her that he's a little brat.

After some fans submit a video of a prank to the web-show, Carly, Sam and Freddie discuss pranks they've pulled in the past, and Carly begins to feel self-conscious about never having pulled any of her own. When she asks Spencer to help her pull one on Sam and Freddie, it sends him on a pranking rampage the likes of which Seattle hasn't experienced since he was in Junior High School.

The iCarly crew meet a fan (Nora Dershlit) who seems normal. She locks them in her basement, and the only person who can save them is Gibby.

Plans for the landmark 50th web cast of iCarly are at risk of being curtailed when Sam gets detention. Realizing she can't do the show without her co-host, Carly and Freddie try to get in trouble themselves, so they can do the live web cast from their school's detention room. However, deliberately trying to get detention proves to be far more difficult than Carly can imagine, and even harder for Freddie.

The iCarly Crew performs sketches on their show that spoof those on "Late Night with Jimmy Fallon," which the host finds so impressive, that he invites them on his show for a rare live performance. Thanks to some of Gibby's usual misfortune however, the cast of both shows almost gets in trouble.
