I try to run a nice, clean, safe town here. A town where a man can sneeze and not get his brains beat out. You follow me?
[on telephone to Tibbs' chief] I do want to thank you for offering such a powerful piece of manpower as Virgil Tibbs.
Just once in my life, I'm gonna own my temper. I'm telling you that you're gonna stay here. You're gonna stay here if I have to go inside and call your chief of police and have him remind you of what he told you to do. But I don't think I have to do that, you see? No, because you're so damn smart. You're smarter than any white man. You're just gonna stay here and show us all. You've got such a big head that you could never live with yourself unless you could put us all to shame. You wanna know something, Virgil? I don't think that you could let an opportunity like that pass by.
Gillespie: [Laughing] I don't think we're going to have any trouble, are we, Virgil?
Tibbs: No trouble at all.
Gillespie: Whatcha hit him with?
Tibbs: Hit whom?
Gillespie: "Whom"? "Whom"? Well, you a northern boy? What's a Northern boy like you doing all the way down here?
Tibbs: I was waiting for the train.
Gillespie: There ain't no trains this time in the morning.
Tibbs: Tuesdays only 4:05 to Memphis.
Gillespie: You say. [train horn blowing] Well, alright. You say right.
Gillespie: Colored can't earn that kind of money [a few hundred dollars], boy. Hell, that's more than I earn in a month. Now where did you earn it?
Gillespie: Just what do you do up there to earn that kind of money?
Tibbs: I'm a police officer.
Gillespie: How much they pay you to do their police work?
Tibbs: A hundred and sixty-two dollars, and thirty-nine cents per week.
Gillespie: A hundred and sixty-two dollars and thirty-nine cents a week? Well boy! Sam, you take him outside but treat him nice, because a man that makes a hundred and sixty-two dollars and thirty-nine cents a week, we do not want to ruffle him!
Mrs. Colbert: I came by to make it as clear as I possibly can: that I do not want the Negro officer taken off this case.
Mayor Schubert: Negro officer?
Gillespie: Yeah, well he, uh... he comes from up North, you see, and he was, uh, kinda... passing through...
Mrs. Colbert: I don't care what he is. If it wasn't for him, your impartial chief of police would still have the wrong man behind bars. I want that officer given a free hand, otherwise I will pack up my husband's engineers... and leave you... to yourselves.
[upon the suggestion that he may have murdered Colbert, Endicott slaps Tibbs across the face. Tibbs promptly slaps him back. Endicott is shocked]
Endicott: You saw it.
Gillespie: I saw it.
Endicott: Well, what are you gonna do about it?
Gillespie: I don't know.
Endicott: I'll remember that. [to Tibbs] There was a time when I could've had you shot.
Mayor Schubert: Bill... what's made you change your mind about Tibbs?
Gillespie: Who says I have?
Mayor Schubert: Last Chief we had... he'd have shot Tibbs one second after he slapped Endicott, claim self-defense.
Gillespie: [regarding Sam Wood's status as a suspect] We have the motive which is money, and the body which is dead!
Tibbs: Sam didn't kill Colbert!
Gillespie: What makes you so sure?
Tibbs: Because Colbert was killed HERE, driven back to town in his own car and dumped on the street. Sam couldn't have driven two cars!
Gillespie: Boy, it would give me a world of satisfaction to horse whip you, Virgil.
Tibbs: [laughing] My father used to say that. He even did a couple of times.
