Off panel: If you believe in yourself, you can do anything!
T-Rex: ...I can?

T-Rex: I CAN?!?

T-Rex: Okay Dromiceiomimus, I believe in myself, utterly and completely, and what I want to do with that belief is get boats for hands so I can walk around and say "wow, these boats sure are handy".
T-Rex: HAND-y, Dromiceiomimus.
Dromiceiomimus: I got it, yeah. I guess we COULD make some boat-shaped gloves that -
T-Rex: NO! They have to be REAL.

Utahraptor: You want to cut off your hands and replace them with ACTUAL full-sized boats?
T-Rex: I believe in myself!

T-Rex: BUT: they still have to work as hands too. They must be actual boats that are also flesh and allow me sensation.
Utahraptor: How about this: if you believe in yourself, you can do SOME things, not all things. Perhaps not even MOST things.

Off panel: But you can do approximately as many things - and perhaps even slightly more - than you could if you DIDN'T believe in yourself.
T-Rex: Okay you know what that's actually WAY more reasonable
