Hugh: Yeah, we're in a different reality because the reality where I am from, my best friend didn't sleep with my wife.

Mike: Hugh, do you not understand what I'm saying? This all started tonight, and if there are a million different realities, I have slept with your wife in every one of them.

Hugh: So, listen to this. This is what he's written. "There is another theory: that two states continue to exist... separate and decoherent from each other, each creating a new branch of reality... based on the two outcomes. Quantum decoherence ensures that the different outcomes... have no interaction with each other."

Mike: No, we're not splitting up. We're just gonna go in two different groups.

Mike: This whole night we've been worrying... there's some dark version of us out there somewhere. What if we're the dark version?

[last lines]

Kevin: [his phone ringing] That's weird. It's you calling me. Hello?

Mike: If we're collapsing right now, I'm gonna collapse on them. I'm not gonna wait for them to collapse on us.

Hugh: Whoa, whoa, Mike.

Mike: I'll go over there and I'll just kill 'em.

Hugh: These are Brian's notes from his lesson plan for his class. "Decoherence and Schroedinger's Cat."

Mike: Let's have a drink.

Kevin: And then, he took me to some lawyer bar.

Em: A lawyer bar?

Kevin: Yeah. A lawyer bar, kind of. I don't know. Everybody there seemed like a lawyer. I felt like I was the only person without a tie.

Em: Well, maybe we should get you a tie for emergencies.

Kevin: Yeah, wardrobe emergencies.

[first lines]

Kevin: [on the phone] I felt like I had a lot of time.

Em: I know. It's good. I'm good.

Kevin: Yeah. We're, um... we're just getting off the freeway.

Em: Yeah? Did, Hugh pick you up at the office, or...

Kevin: Yes, he was coming in from Oakland. He was late, of course. Then I took him... And then, he took me to some lawyer bar.

Em: A lawyer bar?

Kevin: Yeah. A lawyer bar, kind of. Yeah. I don't know. Everybody there seemed like a lawyer. I felt like I was the only person without a tie.

Em: Well, maybe we should get you a tie for emergencies.

Kevin: Yeah, wardrobe emergencies.

Laurie: Em, you seem to be the comet expert here. What happened the last time?

Em: This one passed over a hundred years ago, but much farther.

Laurie: But do we know about anything that happened?

Em: Nothing happened then, it was too far away.

Laurie: So, is there any reason we should be freaked out right now?

Em: Well, I mean, it is a lot closer this time.

Laurie: What does that mean?

Em: Okay. I read one more thing...

Lee: Oh, another story!

Em: Just one more. It's called the Tunguska Event, and, um, it was a comet or a meteor or something like that, that entered the atmosphere over Siberia and exploded over Earth. So it didn't actually have physical impact. It didn't touch Earth, it didn't leave a crater or anything, but the force of that explosion flattened trees for hundreds of miles. But it only killed about one to two people.

Laurie: It's Siberia. There were probably only two people there.

Em: Yeah, but they don't necessarily...

Mike: [jokingly] It wiped out the population of Siberia.

Laurie: Basically, yeah.

Em: Right.

Laurie: Well, that doesn't make me feel better.

Kevin: And when was this?

Em: It was like, in 1908, 1903...

[Suddenly they hear someone banging on the door and get startled]

Amir: [Looking at his picture from inside the box] This was taken tonight.

Em: What? How do you know that?

Amir: I bought this sweater today, so that's from tonight.
