The line comes from The Simpsons, where Apu Nahasapeemapetilon runs the Kwik-E-Mart in Springfield and repeats the phrase to almost every customer. Voiced originally by Hank Azaria, it became Apu's best known catchphrase during the show's 1990s peak and was quoted widely in everyday conversation. As clips moved to soundboards and short form video, the farewell was reused out of context as a generic, slightly mocking goodbye. Its lasting appeal is its instant recognition, even for viewers who have not watched an episode in years.
