T-Rex: There was a time where we didn't know which organ did what! We cut open our bodies and we were like "Whoah, THAT'S a hot mess. I have NO IDEA what's going on in there."

T-Rex: "Don't hassle me with your guts, bro; I can't even begin to deal with that right now!"

T-Rex: But then we got smart and figured it out! This has been.... A Tale Of History.
Dromiceiomimus: If there was a time when we didn't know what organs did what, wouldn't there also be a time when we didn't know how sex worked?
T-Rex: OH DANG, there totally was! Hah hah hah!

T-Rex: We were such losers!!
Utahraptor: Hah hah! ZING!

T-Rex: "Duhh, where do babies come from?"
Utahraptor: "I don't know because the reproductive consequences of the sex act manifest only infrequently, and when they do it's a long time after the sex was performed! Duhhhhh!!"

Narrator: LATER, T-REX IS VISITED BY A TIME TRAVELLER FROM THE FUTURE:
Off panel: "Duhhh, I don't know how cold fusion works and whenever my body dies my consciousness dies as well!!"
T-Rex: ...That is an accurate representation of my whole deal, yes
