Plot
Mordecai and Rigby find a newspaper ad posted by Benson desperatly wanting groundskeepers so they answer the advertisement to Pops, who gives them the job. They get their bedroom (which is empty at the time), and drink two cases of soda while bringing in a pile of old clothes, a blanket, a pillow, and an alarm clock. When they wake up the next morning, they go downstairs to eat breakfast, only to realize that there's one clean bowl an spoon left for cereal, they play punchies for it; due to Rigby's lack of muscle, Mordecai wins the bowl for cereal and the spoon. Benson and Pops come in, carrying an old small sofa and Mordecai and Rigby follow them outside to claim the chair. Pops says that they are leaving the chair where the men whisk it away to Magic Trash City, but Benson simply says they are throwing it away; next, the latter drives away, leaving Mordecai and Rigby skeptical about the explanation. However, both of them find it uncomfortable, which explains why Benson explained that they were throwing it out; yet, Mordecai and Rigby play Rock, Paper, Scissors for the couch.

After tying for the one hundredth time, a black hole enters with a monster inside who begins to eat the chair so Mordecai and Rigby run for cover at the doorstep but Rigby runs back when he sees the chair moving closer to the hole. Mordecai goes after Rigby, leaving Pops after both: Pops clings onto a lightpost while Mordecai clings onto Rigby who clings onto the chair. Pop's grip on the lightpost is released, but they are caught by Skips as they slid to their death, the latter telling everybody to pass on the message of holding on, but when Mordecai says it he sees that Rigby has his head inside the hole! Benson drives the cart slowly, pulling Rigby out but it hits the garage so Benson tells the two to end the tie and Mordecai tells Rigby his move and despite Rigby's doubts, they throw down one last time.

Afterward, the black hole is gone and the park is a mess. Mordecai asks Rigby if he won, but Rigby replies that he probably failed to hold onto the chair, but it is still remaining, one side horribly burnt. Benson screams at the two to flip the cart over, throw out the chair, and clean up the entire mess or they'll be fired; afterwards, he, Pops, and Skips leave, as the two then play a game of rock, paper, scissors for who to drive the cart, ending the episode there.

Trivia

 * This episode is a remake of the show's original pilot episode from the 2009 scrapped CN project called The Cartoonstitute.﻿ Alongside "Uncle Grandpa" (Later the basis for Secret Mountain Fort Awesome), the show's pilot was a sucess.
 * In the pilot Rigby states, "those rooms aren't cool, there's nothing in them. I had to sleep on the floor last night." ﻿meaning that they had seperate rooms in the pilot but they share a room in the show.
 * In the episode it's said that Benson was originally supposed to be the "immortal" one but Skips took that role yet here, the former tells Mordecai and Rigby that "You have to break the tie!" a scene that should have been cut in order to keep the show canon, but it was a recreation of the pilot.
 * 6 more clips are added to this episode as opposed to The Pilot
 * Muscle Man told a "my mom" joke in this episode; he hasn't told one since Muscle Woman.
 * Pops thinks Muscle Man's "my mom" jokes are funny in this episode.
 * This episode is now the most viewed of all time; over 2.6 million people watched its premiere.
 * It plays "I'm Alright" by Kenny Loggins, the Theme from the 1980 comedy golf movie, Caddyshack, this is a possible pun considering that, similar to Carl in the movie, M&R are groundskeepers for a park.
 * This is the first licensed-music episode since Death Punchies.
 * In this episode, the video game console is already in the house before Mordecai and Rigby are hired. In previous episodes, it is implied that they bought the system themselves.
