God: T-REX WHAT IS YOUR FAVOURITE SHADE OF BROWN

T-Rex: Dude! It's this delightful deep brown, kind of a burnt umber?

T-Rex: It was a super popular colour with 16th and 17th century painters. It only stopped being made when we used up the necessary ingredients.
Dromiceiomimus: Really! Which ingredient did we use up?
T-Rex: Well I don't want this to be a "thing", Dromiceiomimus, but it's called "mummy brown" and it's KINDA made from ground-up mummies.

Utahraptor: It's "kinda" made from ground-up mummies?
T-Rex: OKAY IT'S LITERALLY MADE FROM GROUND-UP MUMMIES.

T-Rex: We dug up actual consecrated remains and ground 'em into dust and painted with them, OKAY?? And we kept it up for generations, stopping only when the corpses ran out. I don't know what this says about us as a people, but we've all just got to live with it. PAINTING WITH GROUND-UP BODIES: A PART OF OUR HERITAGE.
