Cisco, Caitlin and others in “Unfinished Business”

Cisco

Man, I don't know what this is. All I know, it just came off the armor of some Hindu speed god, so...

Caitlin

It's like the box the Philosopher's Stone came in. It simultaneously exists, it doesn't exist.

H.R.

Like Schroeder's Cat. Remember? Schroeder? Guy with the cat, in the box, both alive and dead at the same time, dun dun dun. Which, by the way, seems like cruelty for animals. Half the time.

Cisco

Okay, I think you're thinking of Schrödinger, maybe?

H.R.

Schro - no.

Cisco

Yeah. 'Cause Schroeder's the guy from Peanuts.

H.R.

I don't think so!

Caitlin

Yeah. The one with the piano.

H.R.

Charlie Brown has the piano. On my Earth, that's the whole gag, 'cause he can't play the piano. He's terrible.

Jesse

Oh my god. Who cares about cats, or pianos, or the frickin' Peanuts?

H.R.

It's not "the" Peanuts. It's just... Peanuts.
