T-Rex: Let's assume everyone makes just one mistake a day! And let me just say, as a guy who mistakenly poured orange juice into his cereal this morning...

T-Rex: ...I believe this to be conservative??

T-Rex: That means - even at just one mistake a head - there's BILLIONS of mistakes made every day, MILLIONS every minute, and a HUNDRED THOUSAND NEW MISTAKES tumbling from our clumsy hands and out into the world EVERY SECOND.
Dromiceiomimus: What the heck, us?! How does ANYTHING get done right at all??

Utahraptor: Man, we're pooched!
T-Rex: We are totally pooched!

T-Rex: If aliens ever arrived who DIDN'T make mistakes, they'd take over in a HEARTBEAT. They'd be like "The inhabitants of Earth evolved to make mistakes... and that was their FIRST MISTAKE."
Utahraptor: I assume the pause is for when they're cocking their spaceguns.
T-Rex: Oh, yes, ABSOLUTELY.

Off panel: I do think it's interesting how quickly you went from "accidentally pouring OJ into your cereal" to "the only logical conclusion is Earth will be subsumed by perfect godlike aliens from space."
T-Rex: I thought about it while eating sour orange-soaked grain!!
