T-Rex: Did you know that mass extinctions happen REGULARLY in our past? Like, every 27 million years or so, a bunch of life on Earth just DIES. This is not a joke. This actually happens.
T-Rex: SUSPICIOUS, yes?

Narrator: CONSPIRACY THEORY COMICS

Dromiceiomimus: Aren't they just asteroid impacts, T-Rex?
T-Rex: That happen regularly over 500 million years? Hah! PLEASE. Asteroids strike at unpredictable intervals, not according to some cosmic clock!
Dromiceiomimus: So what do you propose: divine intervention?
T-Rex: No. My friend, I propose nothing less than CONSPIRACY.

Utahraptor: Someone's attacking us from... space?
T-Rex: Not someone: some-THING. An entity known only as NEMESIS.

T-Rex: A red dwarf star in SECRET ORBIT around OUR OWN SUN. Every 27 million years it returns, disturbs comets in the Oort cloud, and death rains down from the skies. All life on our planet, eternally cursed by a single wayward star.
Utahraptor: And the clock is ticking.

Narrator: LATER T-REX FINDS OUT THIS IS AN ACTUAL SCIENTIFIC THEORY CALLED "THE NEMESIS HYPOTHESIS":
T-Rex: Well! That's awesome.
T-Rex: On a side note, I see nothing wrong with a petition to replace "hypothesis" with "conspiracy theory" in all the hard sciences?
