Gerbil walks up pulling two six-packs of tall cans of green pop in a red wagon, "Aunt Twistine," Gerbil enquires, "That was a long pull, what do I get for all that work?"
Twistine looks down at Gerbil and tells him, "Why of course you can have the empties, should be able to turn them in and get something."
Gerbil frowns, "But Aunt Twistine, that murky green pop is canned in steel cans, those aren’t worth nothing."
"Might be a deposit on ’em," Gus suggests.
"Two states over there is," Gerbil replies, "But I can’t pull this wagon that far."
