The line 'thank you, come again' is the signature catchphrase of Apu, the Indian-American convenience store owner on The Simpsons, voiced by Hank Azaria from 1990 onward. It became one of the show's most quoted goodbye lines and a staple of soundboards and meme edits. Spanish dubs of the show adapted it as 'Gracias, vuelva pronto', and fans commonly misspell it 'vuelvas prontos', which is how the clip is usually labeled online. It persists as a lighthearted way to end videos and poke fun at service-industry goodbyes.
