While the show generally manages to avoid this by having Mordecai and Rigby hardly have any affecionate moments, it still shows up.
- Mordecai and Rigby do a Security Cling to each other in "Don"
- Mordecai being awfully defensive of Rigby in "Eggscellent" gives off this vibe.
- Mordecai, Benson and Rigby all saying "I love you" to each other in "Blind Trust"
- Benson and Pops tend to have these moments sometimes, because they tend to work together a lot and quite a few situations result in Benson holding Pop's hand or trying to protect him.
- The closeness of their relationship was really evident in the finale, when, after Pops dies, Benson is the one who places flowers on his grave.
- Benson has a hilarious moment in "Dodge This" in which he, drunk (ate?) on chicken wings and suffering from a concussion from dodgeball, leans in really close to Mordecai and whispers very loudly, "I like you better than all of the guys."
- Not in the animation, but issue #13 of the Regular Show comic book has the short story Mordecai and...
- In "Hello China", a couple of Benson's female students hold hands as they're leaving class, though in Chinese culture this can be romantic or platonic.
- Andy, (the Baby Ducks' older brother) is seen in the finale with two people in his spaceship's cockpit. One male, one female and the male has his arm around Andy. He also has a voice that leans on the wall of being the stereotypical sassy gay accent.
- In Rigby's Body, we get this exchange from Skips and Rigby:Skips: We tried it the nice way, now we do it the Skips way. [BOOM BOOM]
Rigby: [looks as though he dropped the soap] - Muscle Man and Hi-Five Ghost have a few moments like this.
- In "Favorite Shirt", while doing his impersonation of Muscle Man, he takes a more genuine approach saying he's "A soft guy deep down."
- "Gut Model" has Fives protecting Muscle Man from a grease monster by using his body as a shield and outright saying he needs him.
- The entirety of "The End of Muscle Man." A lot of the other guys reactions read as friendship, but Fives' reactions all feel like they could be construed as something more, especially their final conversation where Fives can't find the right words to say and Muscle Man just shushes him, saying he doesn't need to.
