South Park, Season 4

[Trying to resolve the dispute over who has been elected kindergarten class president]

Mr. Garrison:
All right, children. As you know, we've been waiting for the absent kid's ballot to come in. Well, his mother was nice enough to bring him in from the hospital so that he could cast his vote. Mrs. Harris?

[She comes in, guiding a sick boy hooked to an IV pole. He hands his ballot to Mr. Garrison and coughs something up onto the floor.]

Mr. Garrison:
Thank you very much, Billy. Don't forget to pick up your lung.

[He picks it up and leaves with his mother.]
