The Flash, Season 3

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.
