After watching videos of the Master Prank Caller, Mordecai and Rigby decided to make prank calls. They successfully did it to the likes of Skips, Pops, and even Benson. Next, they're going to prank call the Master Prank Caller, but before they could do so, Benson shows up really pissed off for their prank call on him that he destroys the phone. They got cellphones from Pops so that they could prank call the Master Prank Caller.
This episode provides examples of:
- Animate Inanimate Object: The Master Prank Caller is a giant 80's cell phone with human arms and legs, even making calls on himself at one point. Averted when defeated and his earpiece shatters to reveal a decrepit human face underneath, suggesting he's a human somehow encased in a cell phone suit.
- Berserk Button: Benson and the Master Prank Caller really don't like getting prank calls.
- Big "NO!": The Master Prank Caller lets out two. First when he realized he's been pranked and the second when Rigby is about to press his power button.
- Cassandra Truth: When Mordecai calls Benson for help, he thinks it's a prank call.
- Continuity Snarl: Regular Show's official media describes Pops as a lollipop from Lolliland. This episode suggests that Pops is genuinely human but with brain tumors because of those 80s cell phones.
- Defeat Means Friendship: When the Master Prank Caller is defeated, he joins Mordecai and Rigby in making prank calls.
- Didn't Think This Through: When Rigby tries pranking the Master Prank Caller, he identifies himself as "Stan". Apparently he didn't think further than that when the Master Prank Caller asks "Stan who?" and all Rigby can come up with is "Stanminson".
- Disproportionate Retribution:
- After finding out that Mordecai and Rigby have been making prank calls, Benson bans them from using the house phone before tearing it out of the wall and smashing it to pieces.
- The Master Prank Caller banishes Mordecai and Rigby to 1982 for trying to prank call him, and when they try again to get back home, he tries to murder them outright.
- '80s Hair: The Master Prank Caller give these to Mordecai and Rigby.
- Everyone Laughs Ending: Mordecai, Rigby and Master Prank Caller after they prank Benson and rob him of his chair.
- Hypocrite: The Master Prank Caller makes a series of online videos of his prank calling other people, but he can't stand it whenever someone tries to prank call him.
- Laser-Guided Karma: Benson gets his chair transported to the 70s by Mordecai, Rigby, and the Master Prank Caller.
- Mythology Gag: Younger Pops has his voice from the original sketch, "The Naive Man from Lolliland", which was a much lower and softer voice than the one he generally uses.
- Reality Warper: The Master Prank Caller can send anything through time, summon anything he wants like clothes or a limo, and can teleport.
- Stable Time Loop: The gang accidentally hit Pops in the 80s. This is how he becomes the scatter brain to be in the present.
- Tin Foil Hat: Mordecai and Rigby wear them while using Pops' phone, after he warns them that old cell phones could cause tumors.
- The Unreveal: We never find out what year they currently live in. When they travel through a long hallway full of doors to different years, the last door says "present day" while the latest visible year on the doors is 2004. Future episodes are never clear either, with technology wavering between modern-day and slightly-dated.
- X Called; They Want Their Y Back: "The [decade] called. They want their [object] back". When it's used, it sends the object back to that decade.
- Your Mom: Mordecai prank calls the Master Prank Caller about being a pizza delivery guy with his 50 pizzas ready. MPC responds, "Sounds great, bring 'em over" with those hot wings because "Your mom's like totally starving".
