Mono-Monday: Money - "Hands off My Stack!"

GoranZebuhr is setting us some great challenges for Mono-Monday this month - many thanks!

To follow this challenge as fully as possible, I decided to take up the second verse of Pink Floyd's "Money", "...keep your hands off my stack...".

PS. Apologies to Bom: I've just noticed she got in before me with this idea. I didn't see hers until after I'd uploaded mine - honest!! Great minds obviously think alike :)
