Several scenes from various sources float around in my head at random times.
In the form of a movie, one of the many films I watched was Dead Mary. Not really the best horror film in the slightest, but in one giggle worthy scene, two of the characters (Who were formerly boyfriend and girlfriend respectively) manage to make the room go quiet after they insult each other. In order to prevent any further awkwardness, one of the other dudes cracks open a beer and says, "Happy New Year!"
In the form of a series, Helluva Boss owns the title of living in my head rent free, specifically two episodes. The one where Blitzo is acting out a three way with himself and little homemade puppets that represent his coworkers, only to be interrupted by Stolas and informed that he needs a bodyguard. This prompts Blitzo to inform Moxxie and Millie that they're going to Loo Loo Land, before pissing off Loona in the process and causing her to shout, "SHUT THE FUCK UP!"
The second episode would have to be where he takes Loona to get her Hellbies shot, and due to the nurse being a frustrating idiot, Blitz loses it and says, "The fucking Hellbies shot, you fucking reeee...ally can't say that word anymore."
In the form of videogames, there's a long list of things that pop up on occasion and crack me up. One example being the sign in the park from The Coffin of Andy And Leyley, which reads "Welcome to bumfukt national park!" (Or something along those lines)
