Some people have suggested that only sick people who like violence can like the movie. But it was praised by both Roger Ebert and Stephen King, so...yeah.
"You accusing me of fucking a CHICKEN, motherfucker?!"
"Boy, the next thing that comes out of your mouth better be some Mark Twain shit, because its DEFINITELY gonna be on your fuckin tombstone!"
"I'M calling the shots! Consider me Willy fucking Wonka! This is MY fuckin Chocolate Factory!"
"Do I STUTTER, bitch?!"
"What's the matter kid, don't you like clowns? DONT WE MAKE YA LAUGH?! Aren't we FUCKIN FUNNY!!?!"
"Does she like it when you puke, I mean, is that, like, part of your thing?"
"Let's give a big round of applause for THE MARRIED FUCKING MAN!"
"FUCK SHIT FUCK SHIT"
"I can still smell your wife's pussy stink on my gun...hope it doesn't rust the barrel."
Sad thing is, it was probably Rob Zombie's greatest work in film, and probably should have let that be the note he chimed out on in film and went back to music because the Halloween remake really fucked up his rep....but The Devil's Rejects is still a great movie, scary, thrilling and funny.
Of course, it was thought of more comically in retrospect because of the famous "Tutti-fucking-frutti" scene.
Otis: (mimic) Hey, man, I think I'm gonna be wanting some ice cream in about ten miles!
Baby: Don't you fuckin imitate me, it's fuckin rude!
Otis: Fuck you.
Baby: Fuck you!
Cutter: Two fucking seconds for the kid, is that gonna kill you?
Otis: Yes, it is gonna kill me! I've calculated the time and two seconds is the exact amount of time that's a hazard to my fuckin health!
Baby: Don't be such a fuckin drag, I'm starving!
Otis: *flips her off* Yeah, eat this.
Baby: What is your fuckin problem? I'm in and out in two seconds!
Cutter: Y'know, I think I'm gonna get me some tutti-fuckin-frutti.
Baby: Tutti-fuckin-frutti, that sounds good!
Baby and Cutter: *Taunting* Tutti-fuckin frutti!
Otis: Shut up!
Baby and Cutter: Tutti-fuckin frutti!
Otis: There is no fucking ice cream in your fucking future!
*Cuts to ten minutes later, and they have ice cream*
