A tramp walks into a jewellers in Oxford Street one Tuesday afternoon.

He
walks around for a while and then sits down on a courtesy couch provided for
people choosing their jewellery.

The dirty git then starts scratching and
picking at his bum hole, joined by satisfying groaning sounds.

People
walking in and out are understandably disgusted and notify the staff about
the tramp's disgusting behaviour.

The manager goes over to him and says
"What the hell do you think you are doing, you dirty undesirable
individual?"

The tramp replies - ' The sign in the window says "Pick your
ring in comfort"'.
