Spy Vs Guy
A retired Russian spy desperately tries to retrieve a secret coin that he accidentally spent 40 years ago.
I got this idea sometime in 2012, when I read that there were several known incidents during the cold war of spies being given secret concealment coins -- and then accidentally spending them. As a result, there are apparently several spy coins still in circulation today.
I'm a big fan of the Chuck Jones/Tex Avery Looney Tunes, especially Wile E Coyote and Roadrunner. Which I guess is pretty obvious when you watch this short.
