Fire Chief's uniform

A police officer, though scheduled for all-night duty at the station,
was relieved of duty early and arrived home four hours ahead of
schedule, at 2 AM.

Not wanting to wake his wife, he undressed in the dark, crept into the
bedroom and started to climb into bed. She sleepily sat up and said,
"Mike, dearest, would you go down to the all-night drug store on the
next block and get me some aspirin? I've got a splitting headache."

"Certainly, honey," he said, and feeling his way across the room, he
got dressed and walked over to the drug store.

As he arrived, the pharmacist looked up in surprise, "Say," said the
druggist, "aren't you Officer Fenwick of the 8th District?"

"Yes, I am," said the officer.

"Well, then, what in the world are you doing in the Fire Chief's uniform?"
