T-Rex: If a tree falls in a forest, does it make a sound?
T-Rex: Answer:

T-Rex: YES, COME ON, HOW ARE WE STILL TALKING ABOUT THIS??

Dromiceiomimus: Aha, but if you define sound as "a pressure wave moving through matter that interacts with the ear", then it doesn't make a sound, because sound doesn't become sound until somebody hears it!
T-Rex: Listen, this little rhetorical trick might have worked in the 1800s, you know, BEFORE WE HAD RECORDED SOUND, but not anymore. Microphones exist! Sound files exist. Sound exists even when nobody is there to hear it!

Utahraptor: But can you truly call a recording "sound"? Surely it's just data with the potential for sound, when played back appropriately.
T-Rex: OH MY GOD

T-Rex: The 1700s philosopher who asked this did not intend for us to argue about "potential sound". He wanted us to question whether the world exists when we're not looking at it, BUT WE ALL KNOW THAT IT DOES, because none of us live in the 1700s anymore where this question could make everyone say "whoa dude" as it blew their minds!!

T-Rex: ...Though of course since it was the 1700s, instead of "whoa dude" they'd say "alack and forsooth, my brethren"!
Off panel: All history more than three weeks old kinda collapses into a single moment for you, doesn't it?
T-Rex: Forsooth, my brethren
