He's a Bully, Charlie Brown (2006 TV Movie)
[Charlie Brown and Marcie are attending the same summer camp. When Peppermint Patty calls, Marcie decides to make Peppermint Patty jealous by pretending Charlie Brown is her boyfriend]
Peppermint Patty: Hi Marcie. I just thought I'd call to see how you and Chuck are doing.
Marcie: Oh, Charles, I can't talk with you nibbling my ear like that.
Peppermint Patty: AGGH!
Charlie Brown: [answers phone] Hello?
Peppermint Patty: Summer school, Chuck! I have to go to summer school! Can you believe it?
Marcie: Ask Charles if he's going to summer camp with us.
Peppermint Patty: Marcie asks if you're going to camp with everyone else while I'm at summer school.
Charlie Brown: I'm sorry, all the lines in this half of the country have gone dead.
Peppermint Patty: Don't you hang up on me, Chuck!
Lucy van Pelt: Camp will be a good experience for you. It will help you to stand on you two feet.
Charlie Brown: Are you going to camp too?
Lucy van Pelt: And leave my good home? Don't be ridiculous!
Peppermint Patty: This camp chow is good. Aren't you gonna eat, Marcie?
Marcie: This kid has been calling me names, sir. I can't eat.
Peppermint Patty: He upset you so much, you can't eat?
Marcie: No, I hit him with my lunch.
Peppermint Patty: Tell the truth. When you and Chuck were at camp, Marcie, did you do a lot of things together?
Marcie: Well, there was the moonlight walk.
Peppermint Patty: Moonlight walk? Aauugh!
Marcie: Well, it wasn't much of a walk. We just got started when Charles walked into a tree.
Kid: Name's Joe Agate. Welcome to camp.
Charlie Brown: I'm Charlie Brown.
Kid: [flicks Charlie Brown's nose] Nice to "nose" you.
[slaps Charlie Brown in the back hard]
Kid: Good to see your back.
Kid: Got any more marbles, kid?
Rerun van Pelt: No, but now that I know how to play, you can give them back, and we can play again.
Kid: Hate to break it to ya, but we were playing for keeps.
Rerun van Pelt: But I'm just a beginner. I didn't know we were playing for keeps.
Kid: You're in the big leagues now, kid. Everything's for keeps.
