It's Magic, Charlie Brown (1981 TV Movie)
Charlie Brown: [after Charlie Brown gets done kicking the football away from Lucy three times]
Charlie Brown: What's the matter?
[He approaches her carrying the football, and walks around her]
Charlie Brown: Did you lose something? Is this yours?
[Throws the football point blank into her chest on "yours". She expresses anger silently, then puts the ball back down in a teed-up position accidentally. Just when she realized how the ball was placed, it gets kicked away from her again]
Charlie Brown: Ha-ha, ha-ha, ha, ha!
Lucy van Pelt: [after Charlie Brown finally reappears from his invisibility and Lucy pulls the ball away from him again] Welcome home, Charlie Brown.
Charlie Brown: I did it! I finally kicked that football!
Lucy van Pelt: Oh, no, you didn't! I just pulled it away!
Charlie Brown: I did it when I was invisible. I did it!
Lucy van Pelt: You can't prove it, Charlie Brown. No one will believe you.
Charlie Brown: [as he comes over to them] Snoopy knows I did it. He made it possible.
Lucy van Pelt: [angrily] Why, that stupid dog of yours couldn't disappear himself out of a paper bag!
[Snoopy growls at her for that, then starts zapping her with a spell]
Lucy van Pelt: Hey, what are you doing?
[She starts rising in the air]
Lucy van Pelt: Put me down, put me down!
[She keeps rising until she is about 10 feet in the air, then stops]
Lucy van Pelt: Hey, hey! You can't leave me up here! Hey!
[Snoopy and Charlie Brown start laughing and dancing around]
Lucy van Pelt: Hey, what about me?
[They both run off, still laughing. Calling after them]
Lucy van Pelt: Hey! Hey, what about me?
Lucy van Pelt: Linus, have you seen Charlie Brown?
Linus van Pelt: Nobody has seen him since Snoopy's magic show. I just spoke to Sally, and she says even when you look at him, you don't see him.
Lucy van Pelt: What's that supposed to mean? That's the dumbest thing I ever heard.
[Snoopy has covered an invisible Charlie Brown in mud]
Charlie Brown: I feel like a chocolate chip cookie.
Charlie Brown: [after falling out his front door while still invisible] This is ridiculous. I can't walk downstairs because I can't see my feet. Snoopy will just have to make me visible again.
[searches for Snoopy, but can't find him]
Charlie Brown: Snoopy? Snoopy?... Snoopy! Now where can Snoopy be? Where is that dog? I just have to find Snoopy. I can't go on like this.
Lucy van Pelt: If that Charlie Brown is still sneaking around invisible, I'll have to be careful. I'm not going to tee up the ball.
[quick pan to the invisible Charlie Brown, panting invisibly, then back to Lucy, tossing the football]
Lucy van Pelt: But if he *is* visible, I'd hate to deprive him of the opportunity to attempt one of his famous place kicks. I think maybe I'll practice a few tees.
[places the football]
Lucy van Pelt: There. That's about right.
Lucy van Pelt: All right, beagle. Here's your magic book. You made Charlie Brown disappear. You'd better make him reappear. Now you start figuring out how to make him visible again, or I'll pound you!
Charlie Brown: [shortly after it starts raining and he's left alone, invisible] It's raining. Where did everybody go? What about me?
Charlie Brown: [after asking Snoopy to make him visible again, Snoopy, unsure how to do it yet, gets a bucket of soapy water, scrubs him down until he's covered from head to toe with soapsuds, then takes the bucket and throws the rest of the water at him, just to watch the suds go away leaving him the same way] A lot of good that did. I'm still invisible, and now I'm all wet.
Charlie Brown: [he scolds Snoopy and Woodstock for laughing while Snoopy practices his magic] You two'd better settle down. The owner of a cat next door just called. He complained about the racket that you two were making. He says it's upsetting his cat, and for you two to stop this racket.
Marcie: And now for the best trick of all: the Great Houndini will now perform the great disappearing act. This calls for another volunteer from the audience.
Lucy van Pelt: [Still woozy from falling out of the air onto her back during the previous trick] Boy, I volunteered once.
[Turns to him, sitting next to her]
Lucy van Pelt: Maybe you should go this time, Charlie Brown.
Charlie Brown: [Speaking basically to Lucy] Me?
Marcie: Yes. The gentleman who just said 'me', please come forward.
Charlie Brown: [to Marcie this time] Me?
Marcie: Yes yes. The gentleman with the large round head, please come right up.
