Narrator: MEANWHILE, IN THE UNIVERSE WHERE T-REX HAS SECRETLY BEEN REPLACED BY A ROBOT:
Off panel: Hey T-Rex, wanna come over for dinner tonight?
T-Rex: Sure, I'd love to!
T-Rex: Can't wait!

T-Rex: But...
T-Rex: ...but I MUST wait??

T-Rex: I can't wait but I must wait - how can this be reconciled?!
Dromiceiomimus: It's no good, dude! You've stumbled into a paradox! A hell of your own design!
T-Rex: This sucks! I can't wait to escape THIS nightmare!

Utahraptor: OH NO. You just did it again!
T-Rex: It's a paradox 2x multiplier!!

Utahraptor: Now you can't wait for TWO things, but you MUST wait to do two things! You screwed up big time, buddy!
T-Rex: I HATE THIS AND I HATE THAT MY SHORT ARTIFICIAL LIFE HAS BROUGHT ME HERE!!
T-Rex: AAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH

Narrator: MEANWHILE, IN OUR UNIVERSE:
T-Rex: Sure, I'd love to come over for dinner! I CAN wait to do this, but - and here I'm speaking purely figuratively, of course - "I can't wait."
Off panel: ...Why are you talking so -
T-Rex: NO REASON
