Movie Theater Choclate Milkshakes is a brand-new episode of Regular Show. It focuses on Mordecai, Rigby and Wally the Worker working extra jobs to get money to pay for movie tickets.
The episode starts with Mordecai, Rigby and Wally watching Monty take his first steps inside his kennel. The three later watch TV and learn that Pirates of the New World 3: The Thirteen Colonies is playing at the Pirate Movie Theater, and it gets Mordecai and Rigby's attention that they will be serving 10 free chocolate milkshakes during the half-hour intermission. Rigby wants to go because he has been a fan of the Pirates of the New World series since 1997, but Mordecai and Wally only go because Margaret and Charlotte are going as well. The trio ask Benson to work overtime to get money for the tickets to go to the concert and he does with encouragement from Pops and Skips. Quickly, they get the job done by drinking coffee; however, the regular $40 tickets are sold out, and they need more money to buy the expensive $500 tickets. They ask Benson for more chores, but Skips does by having them mow the lawn, but they run out of energy and coffee and end up being tired; fortunately, the Star Wars droids R2-D2 and C-3PO are willing to supply them with coffee in exchange for something else. They do the lawn mowing and manage to get their money and get the tickets, but the droids want their tickets too, so they knock them unconscious with the song "Yodel-Adle-Eedle-Idle-Oo" from Walt Disney's Home on the Range, steal the tickets along with their Fist Pump gadgets, and try to get to Pirate Movie Theater by stealing the golf cart. Mordecai, Rigby and Wally chase them with the lawn mower, and retrieve their tickets, but instead split the tickets in half, allowing them all entry. But once they get to their seats, Mordecai and Wally learn that Margaret and Charlotte have boyfriends, who insult them but they tell them to stop being jerks; then, Mordecai, Rigby and Wally fall asleep once the movie reaches the battle sequence, reducing every bit of their hard work into absolutely nothing!
