This is a very poorly written out idea I had.
At the end of 'Does Pavlov Ring a Bell?' Sparky and Buzz were going to M.I.T. (Medical Institute of Technology?) somehow.
What happened there or could have happened there?
So idea + love rats + boredom = Sparky-centric one shot.

(Light flashes)
Man 1: "What's that?"
Man 2: "Don't know. Let's check it out."
Man 1: "It's coming from in there."
Man 2: "Isn't that where those animals the cops sent over are?"
Man 1: "Yeah. They checked out ok, but it's not like we can just throw them in with the others.
I don't know what the cops were thinking sending them here.
We can't risk contamination. That's why these two are in here and not the lab."
Man 2: "Guess somebody could take them home as pets or something. ...
Well look at that!"
(The room is dimly lit by the glow of a small T.V. A rat is sitting on top of the sofa in front of the T.V.)
Man 1: "How did he get out of his cage?
Wait ... Is he actually watching T.V.?"
Sparky: "Huh? Hello."
(The two men whisper to one another)
Man 1: "Did that rat just talk?"
Man 2: "That rat just talked!"
Man 1: "Do you know what this means? This is amazing! Intelligent rodents!"
Man 2: "We could make a million!"
Man 1: "Could we ..."
Man 2: "Yeah. Sell the rat and -"
Man 1: "No, no. I mean could this - this smartness be passed on you know like genetic or something?"
Man 2: "Wow. But how could -
(The men chuckle as the scene fades out)

------------------------------------------------

Man 1: "This one didn't turn out how they wanted. They said I could have her.
Man 2: "What makes you think she'd be a good match for our little guy in there.
Man 1: "I've been keeping my eye out for the signs. She'll do.
Man 2: "Wonder if that electricity thing will pass on."
Man 1(shakes his head): Keep dreaming, Fred."
(Man 1 opens his hands and deposits a white rat onto sofa next to the first rat).
White rat(thinking): " Just a day. Just an ordinary day, trying to get by.
Just a boy, just an ordinary boy.
... as he spoke he spoke ordinary words, although they did not feel real ...
... for I felt what I had not felt before ...
"

(The white rat licks her tiny pink newborns while Sparky sits near by)
White rat: "Aren't they beautiful?"
Sparky(confused): "What is?"
White rat(smiles): "The children."
Sparky: "There sure are a lot of them."
White rat(proudly): "'m hm. There's seven of them."
