The Simpsons [SEP] Idioms
A number of neologisms that originated on "The Simpsons" have entered popular vernacular. Mark Liberman, director of the Linguistic Data Consortium, remarked, ""The Simpsons" has apparently taken over from Shakespeare and the Bible as our culture's greatest source of idioms, catchphrases and sundry other textual allusions." The most famous catchphrase is Homer's annoyed grunt: "D'oh!" So ubiquitous is the expression that it is now listed in the "Oxford English Dictionary", but without the apostrophe. Dan Castellaneta says he borrowed the phrase from James Finlayson, an actor in many Laurel and Hardy comedies, who pronounced it in a more elongated and whining tone.
