South Park, Season 18

[Cartman is sent to Principal Victoria's office and she confronts him about using the girls' bathroom]

Principal Victoria:
I want to know just what makes you think it's okay to go inside the girls' bathroom.

Cartman:
Because I'm transgender. I looked it up, that means I can use the girls' shitter.

Principal Victoria:
You are not transgender, Eric. You don't even know what that means.

Cartman:
Yeah-huh, it means I live a life of torture and confusion because society sees me as a boy but I'm really a girl.

Principal Victoria:
All right. Well, if you identify yourself as a girl, you must find yourself attracted to boys. Is that right?

Cartman:
That's actually not true. I can be transginger without it having anything to do with the ginger I'm attracted to. Check the state bylaws.

Principal Victoria:
All right, listen, Eric…

Cartman:
Erica.

Principal Victoria:
Listen, Eric. You must know why we can't have you in the girls' bathroom.

Cartman:
All I know is I'm transginger, and you can't make me go to the bathroom with the cisgingers.

Principal Victoria:
With the what?
