T-Rex: If something "isn't worth the paper it's printed on", then it's worth about a penny and a half, assuming it's one page long and printed on paper that came in a 500 pack at current retail rates ($7.99).

Narrator: QUANTIFYING COMMON EXPRESSIONS

T-Rex: Of course, these printouts are worth less if you bought the paper in bulk, and worth more if it takes up multiple pages or it's printed on nice, heavy-stock paper.
Dromiceiomimus: Still: not worth a ton!
T-Rex: But it's worth MORE than something that's "a dime a dozen," as those things cost LESS than a penny each.

T-Rex: But fascinatingly, since it costs "a penny for your thoughts"...
Utahraptor: I like where this is going!

T-Rex: ...something that's not worth the paper it's printed on CAN be exchanged for what someone's thinking.
Utahraptor: Cool! I'll go print out some garbage, and you'll tell me your innermost thoughts!

T-Rex: Fair enough! I'll give you my two cents' worth.
Off panel: Whoah whoah whoah! One cent's worth is fine, thank you.
Off panel: I'm not made of lousy documents over here
