Horton the Elephant struggles to protect a microscopic community from his neighbors who refuse to believe it exists.

Katie: In my world everyone is a pony, and they all eat rainbows, and poop butterflies.
Horton: A person's a person, no matter how small.
Horton: I meant what I said and I said what I meant. An elephant's faithful one hundred percent.
The Mayor of Who-ville: I have 96 daughters and 1 son.
Horton: [laughing] Whoa! Busy guy.
Tommy: We won't tell anyone. And if we do, we'll tell them not to tell anyone.
The Mayor of Who-ville: Horton is a giant elephant in the sky!
[Everyone looks up]
The Mayor of Who-ville: . Don't bother looking, he's invisible.
Horton: I meant what I said, and I said what I meant.
Morton: [sighs] An elephant's faithful one hundred percent.
Horton: That's my code, my motto.
Councilman: This is the chairman...
Horton: Idiot! You're finished in this town! Is that understood? Finished! You Boob!
[brief pause while the chairman splutters]
Horton: I'm just joking.
Councilman: Eh heh, good one.
The Mayor of Who-ville: Horton, I'd like you to meet my wife, Sally.
Sally O'Malley: You exist! This means my husband isn't crazy. Hooray!
The Mayor of Who-ville: And these are some of my daughters, Hildy, Helga, Hula, Heidi, and Hedy.
Hedy, Heidi, Hildy, Helga: Hi!
The Mayor of Who-ville: And this is Miss Yelp, my loyal assistant. And this is Dr. Larue.
Dr. Mary Lou Larue: You saved us!
The Mayor of Who-ville: And Burt from Accounting, and Mrs. McGillicuddy. And Mr. FarFloogin of the Cloogin FarFloogins. And the old man in the bathtub.
Sally O'Malley: Honey, let's not overwhelm the poor guy, he's never gonna remember all these names.
Horton: Well, I'll try my best: Sally, Chairman, Hildy, Helga, Hula, Heidi, and Hedy. Miss Yelp. Dr. Larue, Burt from accounting, Mrs. McGillicuddy, Mr. FarFloogin of the Cloogin FarFloogins. And wasn't there an old guy in a shower?
The Mayor of Who-ville: Mmm, Bathtub.
Horton: [a bit mad he didn't remember the name] Oh, Yeah!
Morton: Just this once, be faithful 99 percent of the time! I mean, I've never gone 99 percent on anything, and I think I'm awesome.
Horton: This entire jungle is a house of death!
Horton: Sorry, this is where we get off.
[slingshots Bad Vlad off tree]
Horton: Cool line, usually I can't think of those things until later.
Horton: Ahaha! To the top of Mount Nool, as fast as lightning, away I go!
Rudy: Mom, Mom! Please, you are so weird, don't do this to me.
Horton: [thanking people] And Morton, for being the only one who stood by me. Well not right by me; he hid in the bushes sending me good thoughts. He's small.
Morton: Dude, you are a warrior poet.
Horton: [In a deep voice as he's hit with a Wickersham banana bomb] Whoa! I can feel the diplomatic processes beginning to break down!
Morton: Horton, the kangaroo has sent Vlad!
Horton: Vlad? Vlad, Vlad... I know two Vlads. There's the bad Vlad... And then there's bunny Vlad, the one that makes cookies!
Morton: ...Yeah, Horton, she's sending you a bunny with cookies. I think it's safe to say it's the bad Vlad.
Horton: Yeah, good call.
Heather: Horton! We've all got our own little clovers with worlds on them!
Jessica: Mine is called Jessica-Land and everyone worships Queen Jessica because Jessica is so beautiful!
Katie: In my world,everyone's a pony nad they all eat rainbows-and poop butterflies!
Horton: We're a club. We're a group. We can take a vote on the issues. We can be a secret society, and no one else can join, unless they wear a funny hat!
Kangaroo: The jungle is not a place for wild animals!
Horton: [in imitation of cheaply dubbed anime] I'll make monkeys out of these monkeys!
Horton: This looks kinda... precarious. Well nothing to worry, obviously when they build a bridge like this they take into account that elephants will be crossing here.
[Horton is being roped while the people of WhoVille make noise to be heard]
Horton: Listen, *please*! It's the most beautiful thing ever!
Yummo Wickersham: I don't hear nothin'.
Narrator: [epilogue] And so, all ended well for both Horton and Who's, and for all in the jungle, even kangaroos. So let that be a lesson to one and to all; a person is a person, no matter how small.
The Mayor of Who-ville: So Jojo, what's uh, what's shakin'? What's happenin'? What's the word?
Horton: [over intercom] Is everything okay down there?
The Mayor of Who-ville: [in shock] Uh... I don't know. You tell me. You're the one holding the speck.
Horton: Alright, I need to get this clover to the top of Mount Nool A.S.A.P.whatever that means. Probably, Act Swiftly, Awesome Pachyderm.
[He sees a rope bridge over a deadly chasam]
Horton: . It's a sheer drop to certain death.
Horton: There's a tiny person on that speck that needs my help!
Horton: I will make monkeys of these monkeys, for it is their destiny!
Narrator: Now some people out there, I think I know who, may find they agree with that sour Kangaroo. There can't really be people as small as a mite. Well, there can and there are, because Horton was right.
The Mayor of Who-ville: [after being told no one believes him] Horton believes me.
Dr. Mary Lou Larue: You shaved ush!
Horton: I have to think light. I'm light as a feather. I am light as a feather.
[a feather lands on the bridge and the plank gives way]
Horton: Heavy feather.
Horton: We must become invisible, travel silently, for there are forces that would seek to destroy us.
Councilman: Who wants the festivities of the Who Centennial to proceed as planned?
[the people of WhoVille begin to cheer]
Councilman: And who wants to celebrate the Who Centennial, in an underground storage area?
Obnoxious Who: *Yeah!*
Vlad: [greedily happy] Oooh! Score!
The Mayor of Who-ville: Seriously, who is this? Is this Burt from accounting?
The Mayor of Who-ville: Listen, Horton, I've gotta go. Apparently there's a problem with a giant meatball.
Horton: You just take care of that meatball sir and leave the freaking out to me.
Horton: [looking down the canyon] It's just a straight plummet to certain death.
Councilman: [to the mayor] Nothing ever goes wrong in WhoVille. Never has, never *will*. You bluthering boob.
Kangaroo: What do you think you're doing?
Tommy: Oh, you guys with worlds are in trouble!
Kangaroo: Have you forgotten what we've discussed?
Horton: Oh no, I'm an elephant and elephants never forget, it's a curse really! I remember, I was on my head and you said hmm and I looked up and you said ,what are you doing?, and I said the thing about the speck, then you pulled my ears and you poked me in the forehead...
Kangaroo: Horton!
Horton: Well you did.
Horton: All right, I gotta get this speck up to the top of Mount Nool A.S.A.P, whatever that means, probably 'act swiftly, awesome pachyderm'! I mean, how hard can that be?
Kangaroo: And that is why my Rudy is pouch-schooled!
