Breaking Bad, Season 3

Walter:
There's been a contamination.

Jesse:
Wait, what? Whoa, hey, hold up!

Walter:
Something got into the lab.

Jesse:
So, uh, what do we do? I mean, do we...wait, wait! Shouldn't we be wearing masks?

Walter:
No, no, it's not that kind of contaminant.

Jesse:
So it's, like, not dangerous? Mr. White, talk to me here!

Walter:
Not to us, particularly, no.

Jesse:
[noticing Walter's homemade fly swatter] What the hell is that?

Walter:
This is, uh, I made it.

Jesse:
Exactly what kind of contaminant are we dealing with here?

Walter:
...Fly.

Jesse:
What do you mean? Fly, like...like what do you mean?

Walter:
I mean, a fly. A housefly.

Jesse:
Like, uh, one fly? Singular? What'd it do?

Walter:
It got into the lab and I'm trying to get it out, okay? Understand?

Jesse:
No, man, not really. I can't say that I'm really following you here. Dude, you scared the shit out of me! When you say it's contamination, I'm thinking like an Ebola leak or something.

Walter:
[scoffs] Ebola.

Jesse:
Yeah, it's a disease on the Discovery Channel where all your intestines sort of just slip right out of your butt.

Walter:
Thank you, I know what Ebola is.

Jesse:
Uh-huh.

Walter:
Now tell me, what would a West African virus be doing in our lab, hm?

Jesse:
So, you're chasing around a fly, and in your world I'm the idiot.
