You Can't Do That on Television, Season 4 (1983)

Mr. Schidtler:
Now class, as we are going on a field trip, I think it is most important [points to the word "BASEX" written on the blackboard] that we know the basics of nature. Can anyone tell me what are the four natural elements of the universe? ... Lisa?

Lisa:
Earth.

Mr. Schidtler:
Right, that's one. Kevin?

Kevin:
Air.

Mr. Schidtler:
Yeah, that's right, that's two. Christine?

Christine:
Uh... fire!

Mr. Schidtler:
Right! And now, Vanessa. Can you tell me what the fourth element is?

Vanessa:
Yeah, but I'm not going to.

Mr. Schidtler:
Well Vanessa, either you tell me what the fourth element is, or you tell me you don't know.

Vanessa:
Well, either way I get something dumped on me. [gets a look of resignation on her face] Okay, water.

[Vanessa is drenched.]

Mr. Schidtler:
[laughing] Oh, it's moments like these that make teaching worthwhile.
