iBust a Thief is the 13th episode of Season 5 and the 107th episode overall.
After an iCarly webcast, Sam notices her laptop is missing. Soon, she messes up Carly's house and tries to find it, to no avail. Freddie gets the idea to access it remotely, so Sam gets the serial number (which she writes on a marshmallow) and they activate the webcam to see an old lady in front of it. They spend the next few hours collecting clues to the lady's location, and when they figure out where she lives, go over there to get the laptop back. Sam notices it is the wrong color though, and Freddie realizes he misread the serial number on the marshmallow. Disappointed that they are probably never going to find Sam's laptop, they return home. When she gets some old pizza from the fridge, Sam finds her laptop in the pizza box and awkwardly walks out without telling anyone.
While Sam is searching for her laptop, she hits Spencer in the face with an old lunchbox. Inside, he finds many tickets for Funk E. Fester's he collected fifteen years ago to get their biggest prize, a plush dolphin, but then misplaced. When he goes to redeem them, the clerk tells him they are outdated and Spencer can't play for points in their new system because he's an adult and is not allowed in the gameroom without a child.
Since Gibby is annoyed with babysitting Guppy, Spencer takes Guppy to Funk E. Fester's so he can enter the gameroom. He spends the entire day playing while Guppy tries to kill the time somehow and eventually wins enough points for the dolphin just before closing time.
- This episode airs one day before Spencer Shay's birthday.
- BooG!e, who portrays T-Bo, tweeted "All good things come to an end...AMAZING opportunity...AMAZING group of people...I grew up on Nickelodeon."
- This episode is the penultimate (second to last) episode of iCarly.
- This is the last regular, half hour episode of iCarly to air.
- Dan Schneider voices the announcer for Bitty Big Heads in the introduction during the web segment Hungry Sam in a silly accent.
- This episode aired on the 26th birthday of Drake and Josh star Josh Peck.
- Mrs. Benson's voice was heard twice this episode but she never appeared in person.
- The Vegetarian Spaghetti Taco was the winning recipe for the Bird's Eye campaign.
- When they show the Vegetarian Spaghetti Taco winner on the screen, the "mmmmm" that is heard is the same soundbite that appears at the end of every episode with the Schneider's Bakery logo.
- Bloopers reveal that they had to do at least two takes of the scene where Gloria bashes Gibby with a lamp 
- Bitty Big Heads is similar to South Park. This is most likely because Dan Schneider is a big fan of South Park. Also, when Sam hands the marshmallow to Freddie she says "hyah" like Cartman.
- The book that Guppy is seen reading in Funk E. Fester's, Nifty Shades of Beige, is a parody of the erotic novel Fifty Shades of Grey. Judging by Guppy's reaction after reading a page of the book, it probably has similar content.
- There was a Hungry Girl ad on the website Freddie used to find Sam's laptop.
- Funk E. Fester's, which is seen in this episode, is a parody of Chuck E. Cheese's.
- Throughout 4th and 5th grade, Spencer used a Spud Monkey lunch box.
- When Spencer was a child, he enjoyed going to Funk E. Fester's because he liked the pizza and weiner nuggets.
- Spencer is thirty years old and he mentioned he won those Funk E. Fester's tickets when was ten. Yet Todd said those tickets are fifteen years old, which would not add up to Spencer's actual age. However, they may have still been using the tickets for five years after he won the tickets.
- Funk E. Fester's closes at 10 PM but when the scene cut to the next one it showed outside and it looked like it was around noon. However, that scene could take place before that one.
- The old lady with the blue Pearbook asks Sam if she wants her kidney back and grasps her abdomen in front on her left side - but kidneys are not located in front in the abdomen, they are located about half-way up a person's back.
- Sam implies that she is Jewish after mentioning that she got her laptop from her Bat Mitzvah. However, in iSam's Mom, she tells the family therapist that she and her mom are not Jewish.
- In iSam's Mom, Freddy says "But, you're not even Jewish" and Sam says not to tell her grandma. Sam is not Jewish. She was scamming her grandma.
- Freddie misreading Sam's laptop's serial number is technically his fault, since he read the 4 as a 9.
- If Sam's laptop was in the freezer for more than 3 days, it should have been damaged.
- On June 1, 2020, the TeenNick airing episode of this started after the commercial break when they are at the Groovy Smoothie. So, the episode was only about 17 minutes, excluding the intro webshow and theme song.
- When the show cuts to the scene showing the Funk E. Fester's building, at the parallel parking lot, it shows the Interstate 295 sign, despite that the iCarly show takes place in Seattle, Washington, but I-295, like the one in Jacksonville, Florida, is an auxiliary route of Interstate 95, which is located on the East Coast of the United States, starting from Miami, Florida in the south and ending in Houlton, Maine in the north. The Interstate Highway that bypasses Seattle is Interstate 405, which is an auxiliary route of Interstate 5, which travels the West Coast of the United States through California, Oregon, and Washington.
