Dan offers to ship Kermit a birthday gift.
No! No birthday present! Right now we’re only “even,” and that’s stretching things a bit!
What if I already got you a birthday present?
Whatever it was, I can’t enjoy it as I sold whatever it was of mine required to enjoy it to get you a birthday present. And whatever that is, you can’t enjoy it because you sold whatever it was of yours required to enjoy it in order to buy me a birthday present.
This is called “life.”
You sold your 1972 collector’s edition full-size Wolverine action figure’s John Wayne utility belt buckle?!
Alternatively: you sold your nose hair?!
