Dennis Mitchell: You're the best Mom in the whole world.

Mr. Wilson:

Margaret: Now then, we can eat, talk, play post office. What would you like to do first, Dennis?
Dennis: Find some way to get you out of my house!

Margaret: [Dennis], you can't be your own sitter.

Dennis: Why not? I'm my own stander.

Mr. Wilson:

Martha, my nerve medicine!

[Mr. Wilson, Henry and Dennis walk up to Officer Grant in the park.]
Mr. Wilson: Oh officer, we'd like a word with you.
Henry: Mr. Wilson, are you sure we're doing the right thing?
Mr. Wilson: Of course I am. Justice will prevail.
Officer Grant: Hello, Mr. Mitchell. Hi Sonny. What's up?
Dennis: Mr. Wilson says I'm old enough to be a citizen!
Mr. Wilson: Never mind the boy, you just pay attention to me. Now first I'd like to point out that we are standing on the sidewalk.
Officer Grant: Well, yes I can see that.
Mr. Wilson: So don't claim that there's grass under our feet!
Officer Grant: Mr. Mitchell, what is this?
Henry: This is Mr. George Wilson. He has something to say to you.
Mr. Wilson: Oh no! You're the one who has something to say. I'm merely a bystander. Now go ahead, tell him.
Henry: Well officer, it's about this ticket you gave me.
Mr. Wilson: By which he means this totally unwarranted ticket which you had the colossal nerve to force upon!
Officer Grant: Is that what you mean sir?
Henry: Well...
Mr. Wilson: It certainly is! He thinks you're completely out of line and he resents it as any red blooded citizen would! Keep talking, Mitchell.
Officer Grant: Are you saying I didn't treat you fair?
Henry: Well officer, it just seemed to me that you could've given me a warning instead of a ticket. After all, that sign's only been there a few minutes.
Officer Grant: Well if it was up to me, I would have. But the law is the law. I don't make it, I only enforce it.
Mr. Wilson: Well he's not accepting your ticket, he's giving it right back to you! Aren't you Mitchell?
Henry: Gosh, I...
Mr. Wilson: Oh, here I'll give it back, let me. (Accidentally rips the ticket from Henry's hands then drops it on the ground)
Dennis: Jeepers dad, you're not supposed to tear up a ticket! I'll pick it right up!
Mr. Wilson: Never mind Dennis, just leave it there. All right officer! What are you going to do about that?
Officer Grant: First, I'm going to write Mr. Mitchell another ticket for walking on the grass. Then, I'm going to give him a second ticket for destroying the first one. That's interfering with an officer in the performance of his duty, you know. (starts writing Henry a third ticket.)
Dennis: Look dad, he's writing you another one. He sure can write awful fast!
Officer Grant: Throwing wastepaper on the sidewalk is against the anti-litter law, Mr. Mitchell. Does that answer your question sir?
Mr. Wilson: Oh, all right! You've won this round, but you'll be hearing from us again!

Dennis (to Miss Cathcart): (approx. line) Are you gonna spin?

Miss C: What do you mean, Dennis?

Dennis: My dad says you're a spinster.

Dennis Mitchell: Helloooooo Mr. Wilson!

Dennis, to Mr. Wilson: Why are you smiling at me like that? Am I unbuttoned someplace?

[repeated line]

George Wilson: Oh, Great Scott!

Tommy (while he and Dennis are giving Fremont a bath): Nothin' smells like a wet dog, does it?

George Wilson: And to think I threw out all my nerve medicine!

Dennis: 3 times 5 is fifteen and you know what? 5 time 3 is fifteen! That's really interesting!

Esther Cathcart: Why don't you come in and have a cookie, while we have a little chat?

Dennis: Okay! Will you let me see you spin?

Esther Cathcart: Spin?

Dennis: Sure! I heard my dad say you're a spinster.

Dennis, to Mr. Wilson: Would you like to sleep in the tent with me and Tommy tonight?

Mr. Wilson: No, I don't want to leave my wife alone.

Dennis: Then we better skip it. There wouldn't be room for her.

Dennis: Can Tommy and me have an apple?

Alice: Tommy and I.

Dennis: Yeah, but what about me?

Grandpa: I'm going to be spending lots of time with Dennis, every minute.
Dennis Mitchell: That'll be so much fun. We can go fishing and eat hot dogs in the morning, and stay up really late.

Dennis Mitchell: I'm not gonna wait until I'm as old as Buzzy! I'm gonna learn to whistle today - if it takes me the rest of my life!
