[the Cartman of the year 2006 is tossing and turning in bed, impatient for a Nintendo Wii, when the phone rings]
Past Cartman: [getting up to answer it] Hello?
[he gets static, until...]
Cartman: [in a higher pitch] Hello?
[Past Cartman is surprised to hear his own voice on the other end]
Cartman: Are you there?
Past Cartman: Who is this?
Cartman: [in 2546, stops K-10 from telling him it's no one] No, no, I have me.
[returns to his past self]
Cartman: All right, all right, listen! Listen to me carefully! You need to be patient!
Past Cartman: [angry] What? Who the hell is this?
Cartman: It's me.
Past Cartman: Me who?
Cartman: Me you!
Past Cartman: What?
Cartman: I'm you in the future! You have to be patient and wait for the Nintendo Wii to come out, or else you'll wake up in the future and have to deal with a bunch of sea otters!
Past Cartman: [sarcasm] Oh, very funny, Kyle!
Cartman: It's not Kyle, it's you!
Past Cartman: Yeah? Well, you can go fuck yourself!
Cartman: [shouts] I'm trying to do you a favor, dumbass! Just listen to me!
Past Cartman: Listen to this!
[farts on the phone, then hangs it up]
Past Cartman: Dickhead.
[the phone rings again, but Past Cartman picks it up and quickly slams it down again]
Cartman: [surprised at his own reaction in the past] What an asshole!
