[JULES] No, I ain't Jewish, i just don't dig on swine, that's all.
[VINCENT] Why not?
[JULES] Pigs are filthy animals. I don't eat filthy animals.
[VINCENT] But bacon tastes good, pork chops taste good...
[JULES] Hey, sewer rat may taste like pumpkin pie, But I'd never know 'cause I wouldn't eat the filthy motherfuckers. Pigs sleep and root in shit, that's a filthy animal. I don't eat nothin' that ain't got sense enough to disregard its own feces.
[VINCENT] How about a dog? A dog eats its own feces
[JULES] I don't eat dog either
[VINCENT] Yeah, but do you consider a dog to be a filthy animal?
[JULES] I wouldn't go so far as to call a dog filthy, but it's definately dirty. But, dogs got personality, personality goes a long way.
[VINCENT] So by that rationale, if a pig had a better personality, he would cease to be a filty animal. Is that true?
[JULES] We' have to be talkin' 'bout one charmin' motherfuckin' pig. I mean he'd have to be ten times more charmin' than that Arnold on Green Acres, you know what I'm sayin'?
