SpongeBob SquarePants, Season 6

SpongeBob:
[gasps] THE SUPER RARE AND PRICELESS MERMAIDMAN AND BARNACLEBOY TRADING CARD! Patrick, where is it?! Where is it?! Neptune, you did not put that in your pocket, did you?! It's getting all bent up! Bent up! [falls on the ground and cries] Bent uuuup! Bent, bent, bent, bent, bent up!

Patrick:
Sheesh. Don't get your pants up in a square knot, SpongeBob. I don't even believe in pockets. I keep everything I need right here. [a bunch of stuff is shown in his back] In the folds of my back fat. [pulls card out of his back] You seem to be pretty fond of this little thing. Why don't you just keep it?

SpongeBob:
You mean... [sniffles] you'd give me your most valuable possession?

Patrick:
I'd give you my most valuable possession? [they hug]

SpongeBob:
You're the best pal ever.

Patrick:
I'm the best pal ever. But can you do me one favor?
