T-Rex: Old units are crazy! Here in the CIVILIZED WORLD -

T-Rex: - everywhere but Burma, Liberia, and oh I don't know THE UNITED STATES -

T-Rex: - we use metric, which has the advantage of making moving between units easy, lets us have a temperature scale based on physical constants rather than "some briny water I found, lol", and of being able to trivially move between scales: making knowing how many centimeters in a kilometer easy, while knowing how many inches in a mile an exercise in saying "I DUNNO, LOTS I GUESS".

Utahraptor: But old units have other benefits!
T-Rex: Pfft. NOT LIKELY.

Utahraptor: They're older, so they're baked into our language! We talk about "walking a mile in someone's shoes", of "giving an inch", etc. And I can tell you're about to say "JUST USE METRIC UNITS" so let me say this: an old English "hogshead" was a large cask of wine, about 300 liters.
T-Rex: So?

Off panel: So a "butt" was an even LARGER cask: two hogsheads worth. And thus "a butt load" was a heck of a lot of wine, and thus NON-METRIC MEASUREMENTS GAVE US "BUTTLOAD"!
T-Rex: Utahraptor! NEVER HAS MY BUTT BEEN SO LOADED!!
T-Rex: (with APOLOGIES to NON-METRIC UNITS, that is!)
