Here's an oldie:
In a funeral home, the family of the deceased had brought his blue suit in which to dress him for the viewing. When they returned later, they noticed that he was wearing a brown suit. When they brought it to the funeral director's attention, he said: "Give me a minute." He wheeled the casket into the next room and reappeared a minute later. The family asked how he was able to change the suit so fast. The funeral director replied: "I didn't switch suits; I just switched heads."
