The scene has Brain being cross-examined
by a lawyer. For reasons that aren't important here,
but have everything to do with his plan to take over the world,
Brain has to convince everyone that he's just a dumb mouse
and the lawyer is trying to show that he's not really a mouse
but a mad scientist.
Paraphrasing, possibly badly, from memory....
Lawyer: What if I told you the moon was made of green cheese?
Would you have a problem with that?
Brain, (scoffing): Hardly. In fact it makes me a bit peckish.
Lawyer: And what if I told you that Albert Einstein was
the lead singer for the Monkees?
Brain, (bristling): Well, I really wouldn't know.
Lawyer: Oh, I see, I see. Did you happen to know,
Mr. Brain, that the Fermi-Dirac distribution is
a soup kitchen over on 51st Street?
Brain, (exploding): The Fermi-Dirac distribution
is the probability a particle with half-integer spin
will be in a given energy state E. My God, man!
Don't you know your quantum statistics?!
Lawyer: I rest my case, your Honor.
It probably has to be seen to be as funny as I remember it.
But I'm LMAO right now recalling it. Oh well. Whew!
Now my next question is, why did they put a cartoon
meant for us physics graduate students on at 10am?
