"Mordeby and Rigbecai" is the seventeenth episode in Season 8 (and two hundred and thirty-fourth overall) of Regular Show. It aired on October 14, 2016.


The guys screw around with a teleportation machine.


After their encounter at UMÄK, The Park is flying through space for their next mission. Mordecai and Rigby are doing inventory in the basement when they find a strange machine: a human-sized, metal box connected by tube to another identical box. Rigby walks in and immediately disappears, only to reappear in the second box on the other side. Mordecai and Rigby realize that it's a teleporter. They start fooling around, such as jumping in it, throwing a football  through it, and firing a gun so the laser shot comes out the other side and hits a stack of soda cans. However, they soon get in an argument over who's turn it is to use the teleporter, get physical, and teleport at the same time. This results with their butts switching; as evident by Mordecai having Rigby's raccoon tail (and one-cheeked butt), and Rigby having Mordecai's blue jay tail. Just then, Benson walks in to the room, asking what they were doing. Without noticing their switched tails, Benson orders them to rake the leaves outside, closes the basement door, and locks it. Mordecai and Rigby have to get Benson's keys in order to open the door and teleport themselves back to normal. 

Muscle Man finds them with their switched tails, and reveals that he was trained as a Teleporter Technician, and that teleporters need to be calibrated before transporting two life forms. He also says that their switched bodies could become worse. Just then, Mordecai's body and arms changes to Rigby's, and Rigby's arms turn into Mordecai's.

Once they obtain Benson's keys, they try to teleport again, but it only makes things worse. This time, Rigby becomes tall and has Mordecai's arms, while Mordecai becomes short, and his body becomes brown like Rigby's. Rigby enjoys his new, tall body, finally beating Mordecai at Punchies, shooting hoops, and running fast from Mordecai, who just wants his body back. Muscle Man catches Rigby, and brings him back to the teleporter room. Once again, Rigby tries to struggle, and all three of them fall in to the teleporter. Muscle Man and Mordecai come out normal, but Rigby comes out as a monster-mix between all three of them, with strength, speed, and muscles. 

Mordecai and Muscle man set up a basketball hoop trap, catching Rigby and teleporting him back to normal. Rigby admits to getting carried away.

Mordecai then tells Rigby to help them put the teleporters back before Benson finds them missing with Rigby saying he will be right there. He then tries to dunk a basketball into the hoop but trips over a small rock.
