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 in the morning.
Not wanting to wake his wife, he undressed in the dark, crept into the bedroom and started to climb into bed.
Just then, his wife "sleepily" sat up and said, "Honey, 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. Feeling his way across the dark room, he got dressed and walked over to the drug store.
As he arrived, the pharmacist looked up in surprise, "Say," said the pharmacist, "I know you - aren't you a policeman? Officer Fenwick, right?"
"Yeah, sure. So?" said the officer.
"Well, what the heck are you doing all dressed up like the Fire Chief?"
