I played poker at Wild Horse Pass Saturday. After I stopped playing I was in the parking garage elevator and two young guys got in the elevator. It was obvious they had not done well. One of the them showed me a slot receipt for 5 cents with a wry look. I said "that's a collectors item, keep it for 50 years and see what its worth". That elicited two smiles as they got off the elevator. They probably thought I was a carzy old guy and had not yet learned no matter what something is someone collects it. This reminded me of a science fiction story read when I was boy.
A farmer has a road side stand selling his produce. One day a flying sauser lands in front of the stand and two little green men get out and walk up to the stand and look everything over. One of them looks down a at a cowpie and asks the farmer "how much for that".
