This clip is associated with Homer Simpson from The Simpsons and is commonly labeled as Homer singing "Under the Sea." Online, it gets reused as a reaction sound for fantasy scenes, blissful denial and comic escapism, especially when a character acts like they have entered a perfect dream life. Its staying power comes from the contrast between Homer's familiar voice and the overly cheerful tune, which instantly signals that the moment is not meant to be taken seriously. It also fits well beside other cartoon reaction audio such as sad song cues.
