Mordecai and Rigby coax Benson into letting them be judges for the Pie Contest being excited to try out a bunch of pies. But they ultimately regret the sheer amount of responsibility put upon them, until a strange animate pie called Promise Pie steps in and offers to take the burden off their shoulders.
Tropes:
- Big Bad Wannabe: Benson, as he wanted to make Mordecai and Rigby miserable, but when Promise Pie rises up, he pulls an Enemy Mine with Mordecai and Rigby telling them how they must defeat Promise Pie.
- Big Bad: Promise Pie.
- Bittersweet Ending: Promise Pie is defeated, and the contestants are satisfied with Pops getting the ribbon. However, Mordecai and Rigby are now stuck cleaning up after the rampage, with the pie fair completely demolished and up in flames. Lastly, Rigby asks what happened to all the free pies they could eat.
- Break the Cutie: Pops feels as though Promise Pie's rampage of devouring everyone is his fault, asking Mordecai and Rigby if his pie was so terrible that he started all this. Mordecai admits that his pie deserves to be recognized as the best, and thus Pops is the first contestant to be freed.
- Break Her Heart to Save Her: When Promise Pie eats Margaret, Mordecai frees her by being honest, loudly telling her how terrible her pie was.
- Brutal Honesty: How Promise Pie is defeated. Whenever Mordecai and Rigby give a full, accurate opinion about the contestants' pies, the contestant is freed and Promise Pie shrinks down.Benson: (as he's about to be eaten) BE HONEST! YOU HAVE TO BE BRUTALLY HONEST!
- The Cameo: Scabitha back from "Crusin" makes a voiceless cameo as one of the contestants who got eaten up by Promise Pie and gets disqualified from the ribbon by Rigby for making her pie too soggy and neglecting to remove a bandage he found in it.
- Cheaters Never Prosper: Muscle Man and Death — and possibly many others — threatened Mordecai and Rigby into giving them the first place ribbon. They all pay the price for this by getting eaten by Promise Pie, then being spat out and forced to go home empty-handed.
- Cordon Bleugh Chef: Except for Pops, Mordecai and Rigby admit that pretty much everyone's pies didn't taste much like pie but rather like buttcheeks, grease, hair or vomit.
- Deal with the Devil: Mordecai and Rigby when they agree to release Promise Pie to relieve their duties as judges for the contest.
- Epic Fail: As Mordecai puts it, somehow Margaret's pie tasted burnt and raw.
- Graceful Loser: Each of the contestants congratulates Pops when he wins.
- Jerkass Ball: Benson sadistically teases Mordecai and Rigby over how difficult their new task is, even suggesting glee in making the contestants miserable. Even after they rescue him from Promise Pie, he still yells at them for the mess.
- Karmic Jackpot: Pops is the winner, and not only did he cook the best-tasting pie, but he was also the only one who didn't threaten Mordecai and Rigby to give him the ribbon.
- Lethal Chef:
- Margaret, which is ironic since she is a line cook for a diner and should've been taught when is food safe and not safe to eat. Her pie looked and tasted the worst, and she doesn't know (or even realize) how horrible it is.
- Death's pie was just filled with a murder of crows.
- Never My Fault: Benson shouts at Mordecai and Rigby for Promise Pie's rampage, even though it was his cruel insults that led to them going to Promise Pie for help in the first place.
- Punched Across the Room: Mordecai and Rigby when they try to pry Margaret out of Promise Pie's grasp.
- Sadistic Choice: Benson forces them between A) staying as the pie contest judges or B) get fired. Both choices are horrible as many people starting with Muscle Man and Death himself are threatening Mordecai and Rigby's lives to give them the 1st Place ribbon and getting fired should be obvious at this point.
- Supreme Chef: Pops, as he won all of the last nine consecutive pie contests.
- Ungrateful Bastard: Benson still shouts at Mordecai and Rigby after they rescue him from Promise Pie, threatening them to fire them if they don't clean up the mess.
