A Stupid Man

An agitated man walks into the store and asks me if we sell any batteries for a keyless entry remote for his car.
"Sorry, we don't, but you can try the Radio Shack about 3 block from here," I sympathized.
"How am I supposed to get there? See.. I am locked out," he replied, swinging his car key from the remote.
Before I even said another word, he disappeared quickly into the night.
When did some of us become so stupid?
