South Park, Season 11

Cartman:
You guys, I got it! Seriously, it's the greatest picture ever! Oh my God!

Stan:
Whatcha do to Butters this time?

Cartman:
It was genius! I waited 'til he was totally asleep, right? And then I got my camera, and I pulled down his pants, and then I took a picture of his wiener in my mouth! [cracks up]

Stan:
Dude!

Cartman:
I know, I know. Check it out. Look. [the other three crowd in and look at the picture] I got his whole wiener in my mouth, see? Ha ha. Oh man, I got him good!

Stan:
Dude, how is putting Butters's wiener in his mouth getting him?

Cartman:
Because that makes Butters gay now!

Kyle:
No, dude, that makes you gay!

Cartman:
Uh, what?

Kyle:
You put a guy's wiener in your mouth, that makes you gay, stupid!

Cartman:
[looks more closely at the picture] Uh-uh.

Kyle:
Yeah-huh!

Cartman:
Kenny, that doesn't make me gay, huh?

Kenny:
Ha ha, that makes you very f***ing gay.

Cartman:
But I'm not--I'm not gay, you guys!

Stan:
You are now.

Cartman:
No--no, it was a stupid mistake!

Kyle:
Doesn't matter. You're gay now.

Cartman:
No, it was just for a second! [puts the picture away] What-what can I do? How-how can I reverse this?

Stan:
You can't!

Kyle:
No--no wait. I-I know how you can reverse it, Cartman.

Cartman:
How?

Kyle:
The only way you can cancel it out is to get Butters to put your wiener in his mouth.

Cartman:
[in low voice] Really?

Kyle:
Yeah. Then it cancels out the gay polarity.

[long silence]

Cartman:
Shoot, I gotta find Butters! [runs off]

Kyle:
Idiot.
