This seems like a great opportunity to share this amusing dialogue from Cosmopolis, a Don DeLillo book and its film adaptation by David Cronenberg:

"There's a poem I read in which a rat becomes the unit of currency."

"Yes. That would be interesting," Chin said.

"Yes. That would impact the world economy."

"The name alone. Better than the dong or the kwacha."

"The name says everything."

"Yes. The rat," Chin said.

"Yes. The rat closed lower today against the euro."

"Yes. There is growing concern that the Russian rat will be devalued."

"White rats. Think about that."

"Yes. Pregnant rats."

"Yes. Major sell-off of pregnant Russian rats."

"Britain converts to the rat," Chin said.

"Yes. Joins trend to universal currency."

"Yes. U.S. establishes rat standard."

"Yes. Every U.S. dollar redeemable for rat."

"Dead rats."

"Yes. Stockpiling of dead rats called global health menace.*
