Fringe, Season 1

Olivia:
Dr. Bishop, I was curious. Did anyone else ever have access to your work?

Walter:
Well, the assistants had bits and pieces. God, I suppose. I suppose the only one that really knew what I was doing was Belly.

Olivia:
Who?

Walter:
Belly. William Bell. He and I shared the lab.

Olivia:
William Bell?

Peter:
You shared your lab with the founder of Massive Dynamic?

Walter:
I'm sorry, I don't know what that is. Massive Dynamic...

Peter:
Ah, nothing really, just a tiny little company. That's perfect. One guy becomes one of the wealthiest men on the planet. The other guy becomes an institutionalized psychopath.

Walter:
Oh!

Olivia:
What? What happened?

Walter:
Oh, I just pissed myself.

Peter:
[smiles] Excellent.

Walter:
Just a squirt.
