Annyong
The little Korean boy on Arrested Development who says "annyong" all the time, which actually means "hello" in Korean, but everyone thinks that that is his name because he says it all the time. Therefore, there is a vicious cycle of annyongs.
Annyong: Annyong.
Buster: Yes, Annyong! Your name is Annyong! We all know you're Annyong! Annyong, Annyong, Annyong!
(Awkward silence)
Maeby: Who's this?
Buster: Oh I'm sorry, this is Annyong.
Annyong: Annyong.
Buster: Yes, Annyong! Your name is Annyong! We all know you're Annyong! Annyong, Annyong, Annyong!
(Awkward silence)
Maeby: Who's this?
Buster: Oh I'm sorry, this is Annyong.
Annyong: Annyong.
