Once Over Lightly

IN TEXAS, another drunk went on a different search--for his doctor. Unfortunately, the doctor had a twin brother, who was a minister. Our poor sot (whose mind was functioning at less than top accuracy, anyway) became hopelessly confused over which brother did what and who lived where. He finally picked one, stumbled up on his front porch, and rang the bell. When the doctor/minister opened the door, the drunk asked, "Do you practice or preach?"
