Charlie had a massive heart attack and died. His body was delivered to the
mortuary. He had been wearing an expensive, expertly tailored black suit at
the time of his demise, so he really looked wonderful, considering the
circumstances.

His wife went to the funeral home to make the final arrangements for his
interment. She spoke to the mortician about what her husband would be wearing.
The mortician pointed out that the man looked really nice in the black suit
he was wearing, and that frankly it would be easier and less expensive to
leave him dressed as he was.
The woman noted that Charlie had always looked his very best in blue, and
that she really wanted him in a blue suit for his trip to eternity. To silence
the mortician's continued outcries, she gave him a blank check and said, "I
don't care what it costs, but please have my husband in the very best blue
suit money can buy for the ceremony."

The woman came back the next day for the wake. To her delight, she found
her Charlie dressed in a gorgeous blue suit with a subtle chalk stripe; the
suit fit him perfectly. She said to the mortician, "Whatever this cost, I'm
very satisfied. You did an excellent job, and I'm very grateful. How much
did you spend?"

To her astonishment, the mortician presented her with the blank check,
indicating there was no charge for these extra services. "No, really, I must
compensate you for the cost of that exquisite blue suit!" she cried.

The mortician responded, "Honestly, ma'am, the change to the blue suit cost
nothing. Funny thing, a deceased gentleman of about your husband's size was brought
in shortly after you left yesterday, wearing an attractive blue suit. I asked
his wife if she minded him going to his grave wearing an attractive black suit.
She indicated that it made no difference, as long as he looked nice...

So I switched the heads."
