호머 심슨의 D'oh! 스페셜 - PART 2
"D'oh!" is a catchphrase used by the fictional character Homer Simpson, from the longest running American scripted primetime television series, The Simpsons, an animated sitcom (1989–present). It is typically used when Homer injures himself, realizes that he has done something stupid, or when something bad has happened or is about to happen to him. All his prominent blood relations—son Bart, daughters Lisa and Maggie, his father, his mother and half-brother—have also been heard to use it themselves in similar circumstances. On a few occasions Homer's wife Marge and even non-related characters such as Mr. Burns and Sideshow Bob have also used this phrase.
