A man who just died is delivered to the mortuary wearing an expensive, expertly tailored black suit. The mortician asks the deceased's wife how she would like the body dressed. He points out that the man does look good in the black suit he is already wearing.

The widow, however, says that she always thought her husband looked his best in blue, and that she wants him in a blue suit.

The woman returns the next day for the wake. To her delight, she finds her husband dressed in a gorgeous blue suit which fits him perfectly. She told the mortician that he did an excellent job, and asked what she owed him.

"There's no charge," he says.

"You see", he goes on, "a deceased gentleman of about your husband's size was brought in shortly after you left yesterday, and he was wearing an attractive blue suit. I asked his wife if she minded him going to his grave wearing a black suit instead, and she said it made no difference as long as he looked nice."

"So", he says, " I just switched the heads."
