Diary

This article is about the season three episode, for the diary that Margaret owns, see here.

Diary is the thirty-third episode of season three (and seventy-third episode overall) of Regular Show. It aired on July 23, 2012.

Synopsis
Mordecai and Rigby must fix a broken lock on Margaret's diary before she returns from vacation.

Plot
Mordecai and Rigby are heading to Margaret's new apartment in a tall building to water her plants while she is away on a weekend trip. While they are looking for a watering can, Rigby takes a hat hanging from Margaret's bedroom door and wears it to imitate Margaret and to make fun of Mordecai, triggering a fight. During the scuffle, they knock Margaret's Diary off of a bookshelf and break the lock. Fearing that the diary's current condition implies that he read through it, Mordecai begins trying to fix it. Rigby gets some glue and while trying to apply it, Rigby puts too much glue on her diary (saying Mordecai made him nervous with his constant emphasis to not put too much on it). Mordecai looks at the container and sees it will come off with heat, so Rigby suggests putting the diary in the microwave oven. When Rigby is about to push start, Mordecai remembers an earlier incident involving a microwave, and rejects using it.

They then decide to put it in the grill on the patio, which caused her diary to catch on fire, so the two decide to extinguish the fire by putting it in the toilet, which works. They then go to Skips for advice who claims that there is a method of using magic to make an exact replica of Margaret's Diary out of another notebook. Skips claims that they must close their eyes during the entire time to not look at the secrets. Rigby opened his eyes on purpose. Then a giant monster known as The Guardian of Margaret's Secrets comes in and Skips announces the only way to defeat it is by telling their true deep secrets. Skips tells his secret that the reason he always skips is to remind him of the time he enjoyed with a woman that he loved and therefore never walks. The Guardian of Margaret's Secrets accept Skips' secret but continues to destroy Margaret's home while Mordecai and Rigby keep telling secrets that aren't deep enough. Finally, Mordecai states that he took away a mail-delivery mattress that was Rigby's and stacked it on his own to be comfortable (explaining why Rigby doesn't have a bed from Ello Gov'nor and The Unicorns Have Got to Go). Rigby also states that he thinks Eileen is hot without her glasses. After this, The Guardian of Margaret's Secrets disappears and all the destruction, including that to Margaret's Diary, has been erased.

The next day, Mordecai and Rigby arrive at The Coffee Shop. Margaret claimed that Eileen stayed at Margaret's the entire weekend to water the plants. Eileen comes out with coffee without her glasses (revealing that she has very small, and squinted eyes). But because of poor eyesight without her glasses, she bumps into a table and spills coffee.

 * This the first time Margaret's apartment appears.
 * This is the first episode to contain a flashback of a previous episode (in this episode, the microwave incident from It's Time).
 * We find out the reason Skips always skips in this episode (he vows to skip for a deceased lover).
 * This is the first time Eileen was seen without her glasses, and the third time we see her exposed pupils (after Brain Eraser and Camping Can Be Cool).
 * It is revealed that Rigby thinks Eileen is hot without her glasses on.
 * This is the second time that Skips says Margaret's name.
 * When Mordecai says "There's just one way to get it back," the captioning accidently miscredits the line to Pops, who is not even in the episode.
 * Benson, Muscle Man and Hi Five Ghost also do not appear in this episode.
 * A truck was seen driving past the coffee shop despite the fact that it was destroyed.
 * Mordecai reveals he uses Rigby's mattress with his own because it's comfortable.
 * This is the first time Rigby used the phrase "STOP TALKING!" since More Smarter, nearly 40 episodes prior.
 * Margaret reveals that Eileen was staying in her guest bedroom looking after her apartment. The day after the incident with the diary Eileen serves Mordecai and Rigby their coffee without her glasses, implying that she heard Rigby state he thinks she's hot without them.
 * This episode has the most secrets revealed by the characters (so far).
 * Goof: When Mordecai and Rigby tustle, Rigby is wearing Margaret's hat. But after the diary falls on the floor, the hat is gone.
 * When Rigby said,"Your Friend without Benefits." is probably a reference to the 2011 Movie, "Friends With Benefits."
 * When Mordecai puts the diary on top of the Grill to remove the glue using heat, it caught on fire, probably because the glue was flammable.
