When Benson discovers that Rigby stole his Grilled Cheese Deluxe, who lied to Mordecai about buying it himself, he forces the two to go to Cheezer's to buy him another one. While they're on an errand to get his sandwich, Mordecai and Rigby decided to have contest on who could lie better.
Tropes included:
- Bad Liar: Rigby tries to lie to Benson and say that the Grilled Cheese Deluxe belonged to him when the bag says "Benson" right on it. When called out, Rigby tries to explain that they somehow spelled his name wrong. Ironically, when he tries to tell the truth of why Benson's new sandwich was burnt to a crisp at the end of the episode, he doesn't believe him.
- Cassandra Truth: At the end, Benson's sandwich is mostly roasted to a crisp. He's bewildered by this, angrily asking what happened. Rigby tries to tell him the truth that they used it to stop a meltdown, but Mordecai bluntly lies and says that they ran over it by accident, causing Benson to believe that and praise him for at least telling the truth.
- Crying Wolf: Played straight when Rigby tries to tell Benson the truth of the entire event straight to his face, but because it was so outlandish, Benson doesn't believe a word he says, not helped by Rigby's already infamous lying streak. Inverted where Mordecai tells him a very simple lie about the sandwich being run over by accident, which Benson believes.
- Curse Cut Short: Rigby: "The only thing you're better than me at is being a big piece of—*punch* OOF!"
- Department of Redundancy Department: "It's supposed to say Rigby, but they misspelled my name wrong." Kinda justified given Rigby's low intelligence.
- Failed a Spot Check: Somehow, Mordecai didn't see that Benson's name was on the bag his Grilled Cheese Deluxe came in.
- Fat Bitch: Mordecai is greeted by an angry obese woman as she tells him that the astronauts can cut in line and when Mordecai is about to tell her that he and Rigby are astronauts she responds in an angry manner.
- Foreshadowing: Mordecai and Rigby pretend to be astronauts for much of the episode, but they eventually become real ones in the final season, which is subtitled Regular Show in Space.
- Forgotten First Meeting: Mordecai attempts to pull this trope off when pretending to know Dr. Asinoskovich, and to his credit, she ends up getting fooled by his lie of having met at a conference she doesn't remember much about, with her becoming flustered.
- Mean Boss: Benson, who after Rigby steals his grilled cheese deluxe and passes it off as his own, orders him and Mordecai to "get off (their) lazy butts and go get (him) another grilled cheese deluxe". It wasn't fair to punish both Rigby and Mordecai, because Mordecai didn't even do anything wrong.
- Nice Guy: Jones and Barry may be willing to threaten violence on anyone pretending to be astronauts, but besides that, they're very courteous to others and are pretty big socialites.
- Serious Business: Astronauts take their job very seriously, at least in this show. They don't take well to anyone pretending to be one.
- Shout-Out: One of the background rockets in the Compound is clearly modeled on Thunderbird 1.
- Ungrateful Bastard: Rigby sees the astronauts as this after they kick him and Mordecai out after they have saved their lives from a meltdown, ignoring the fact that they caused the meltdown in the first place.Jones: If you ever lie about being astronauts again, you're dead!
Rigby: We saved the city, astro—! (they throw the grilled cheese deluxe in his face)
