You Son of a Bitch, I'm In

Origin

The line comes from the Rick and Morty episode “One Crew Over the Crewcoo’s Morty,” the third episode of Season 4, which premiered on Adult Swim on 24 November 2019. The episode is an extended parody of heist films such as Ocean’s Eleven. Frustrated that Morty wants to pull a heist, Rick sets out to prove heists are formulaic by building “Heistotron,” a robot that plans the perfect heist — which promptly goes rogue and begins scheming on its own, forcing Rick to build “Randotron” to counter it. Throughout, a running gag has each newly recruited crew member respond to a slick pitch with a delighted “You son of a bitch, I’m in.” The bit escalates as the scheme grows ever more convoluted, with target after target instantly enlisting.

What it means / how it’s used

The phrase signals instant, enthusiastic, all-in agreement the moment a proposal wins you over. It fits any situation where someone is sold on an idea, purchase, or scheme after a single convincing line — the joke being the gleeful, impulsive speed of the buy-in. In practice it works as a reaction: you quote it, or post a character image macro, alongside whatever tempting pitch just hooked you.

How it spread

The episode’s heist-recruitment gag was instantly quotable, and screenshots and image macros spread to Reddit, Twitter, and Facebook in the days after it aired. Know Your Meme catalogued a “You Son of a Bitch, I’m In” template on 9 December 2019. Imgflip and other meme generators added blank templates, and the phrase quickly detached from the show to become a generic caption for enthusiastic agreement.

Notable examples & variations

• Image macros of the Rick and Morty characters captioned with whatever pitch just convinced the poster.
• “Tell me [X]… you son of a bitch, I’m in” text posts reacting to tempting offers.
• Two-part setups where a persuasive line is followed by the catchphrase as the punchline.
• Reaction use in comment threads to signal immediate, no-questions buy-in.

Legacy / cultural impact

“One Crew Over the Crewcoo’s Morty” is remembered as much for spawning this catchphrase as for its plot, and the line has outlived its episode as everyday internet shorthand. It sits alongside other Rick and Morty exports that became standalone memes — a reminder of how efficiently a single well-delivered throwaway line from the show travels once it reaches meme generators. Rick and Morty, created by Dan Harmon and Justin Roiland, has been an unusually productive meme engine — from “Pickle Rick” to the fan campaign over McDonald’s Szechuan sauce — and this catchphrase is one of its cleanest exports, a line whose comedy survives being stripped of all context. Years on, it remains a common way to announce eager, no-hesitation commitment.
