Mr. Schidtler and Martin in “Pets”

Well, we have a few seconds before the end of class. Could anyone tell me who "Paffloff" was?

He was a scientist who worked with dogs.

Very good. And, you know, by making his dogs respond to the sound of a bell, Pavlov was able to prove that any animal, no matter how intelligent, could be conditioned.

That's the stupidest thing I've ever heard in my life.

I rest my case.
