A dirty old vagrant walks into a jewellers store,lays on the floor and starts picking at his backside and moaning!

The shop assistant is mortified
"Stop that and get out you filthy old tramp!" she yells at him.

"You want to make your minds up" yells the scruffy hobo and points at the sign in the window which says

"Please come in and pick your ring in comfort"

I would rather die on my feet than live on my knees!
