A man who just died is delivered to an Arkansas mortuary wearing an expensive, expertly tailored black suit. Bubba the mortician asks the deceased's wife how she would like the body dressed. He points out that the man does look very 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. She gives Bubba a blank check and says, "I don't care what it costs, but please have my husband in a blue suit for the viewing."
The woman returns the next day for the viewing. To her delight she finds her husband dressed in a gorgeous blue suit with a subtle chalk stripe; the suit fits him perfectly. She says to Bubba, "Whatever the cost, I'm very satisfied. You did an excellent job and I'm very grateful. How much did you spend?"
To her astonishment, Bubba presents her with the blank check. "Dere's no charge," he says.
"No, really, I must pay you for the cost of that exquisite blue suit!" she says. "Honestly, ma'am," Bubba says, "it didn't cost me a ting. You see, 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 missus 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, I just switched the heads."
