Rick and Morty, Season 1

Morty:
You know, Rick, when I first saw all those Ricks and Mortys, I thought, "Gee, that kinda devalues our bond." But then I realized it just means that our relationship must be pretty special to span over all those different timelines.

Rick:
Yeah, it's gotta be that way. You're a camouflage.

Morty:
Camouflage? Wh-wh-what are you talking about, Rick?

Rick:
Ricks have a very distinctive and traceable brainwave due to our genius. The best way to hide from an enemy's radar is to stand near someone with complementary brainwaves that make ours invisible. [picks his pen] See, w-w-w-when a Rick i-is with a Morty, [writes diagram] the genius waves get canceled out by the, uh... ahe-hem... Morty waves.

Morty:
Um... because... our personalities are so different?
