Mordecai must get the memory of seeing Pops naked out of his head.


Mordecai and Rigby find Pops' copy of Moustaches Monthly, which they were to deliver weeks ago. The pair play "Rock, Paper, Scissors" to see who has to deliver Pops his magazine, and Mordecai loses. Mordecai drops the magazine off in Pops' room, but Pops has just exited the shower. Mordecai sees Pops naked and they are both hugely uncomfortable with the situation.

Mordecai goes back downstairs and tells Rigby about his encounter with Pops. Rigby laughs at first, finding it funny that Mordecai has seen Pops' "junk mail", but Mordecai is truly upset. Rigby decides that Mordecai needs to play Strong Johns at the arcade to relieve him of his trauma. This does not work, so Rigby takes Mordecai to see Margaret, but Mordecai can only see Pops' head on Margaret's body. Finally, Rigby and Mordecai go to a video store to rent Good Cop, Sad Cop. Rigby talks to VG and Rigby sees an opportunity to cure Mordecai of his bad memory with a video the employee is obsessed with.

Rigby forces Mordecai to watch Planet Chasers: Starlight Excellent. The animated video does get Mordecai to stop thinking of Pops, but it also saps all of Mordecai's memories and thoughts. Rigby tries to get his friend back by taking Mordecai out for their usual fun activities - bowling, throwing bologna on Muscle Man's car, going for coffee - but Mordecai still remains rather zoned-out. Rigby finally turns to Skips for help - he tells him they must both watch the tape.

The three sit down to watch Planet Chasers together, and this time Rigby and Skips have their memories sapped as well, drawing them all into the video-world - where the real Mordecai is stuck inside. Mordecai tells them that he still remembers seeing Pops naked. At first, Rigby told him to just get over it, but Mordecai explained to him that it was not something that you can just forget or unsee. Skips said the only way for Mordecai to forget about seeing Pops naked, is to erase that memory. They have to search through Mordecai's whole mind to find the memory of Naked Pops. When they find it, the Naked Pops-Memory tries to escape them. Because the event happened so fast in real life, Mordecai's memory is also a fast runner.

Mordecai starts remembering obstacles in order to hinder Naked Pops-Memory's path, even recalling a steep cliffside, but Pops' Memory jumps off it without caring about it. In the golf cart, Mordecai decides to drive off a steep cliff and cover the Naked Pops-Memory once and for all in mid-air, remembering to recall a bouncy jumping castle at the last second to break the trio's fall.

On the ground, they find the video store clerk. The clerk tells them the way out of the video and Mordecai, Rigby, and Skips are soon back into the world of reality. While Mordecai is celebrating his memory's displacement, Benson walks into the living room, fussing about something. While Benson is castigating everybody, his body-towel slips off and his slot pops open, leaving Mordecai, Rigby, and Skips wide-eyed.




  • This episode marks the debut of Eileen, Margaret's best friend.
    • It should also be noted that Eileen's design is slightly different in this episode, particularly her eyes, which are simple black pupils. She also is wearing black glasses unlike the red glasses she would wear later on.

Production Notes

  • J.G. Quintel was afraid that this episode would only air once due to its subject matter. To his surprise, the episode was made and aired without any complaints and continues to air in re-runs.[1]
