A lady's husband dies. She heads to the funeral home to make arrangements. 

She's emphatic that the arrangements must be done with elegance, and attention to detail.

"For example," she tells the funeral director, "I want no wooden chairs. Only padded ones. All the comforts possible to be extended to the mourners. Have the air conditioning set to a perfect 72 degrees. The flowers should be beautiful, yet not overpowering in their scent."

The funeral director takes it all down.

The day of the funeral the widow is examining the viewing room. She notices that the funeral director has not yet turned on the air conditioner. She orders the director to turn it on so that when the viewing starts, the room will be a perfect temperature.

As soon as the air conditioner is on, though, she notices her deceased husband's hairpiece is flapping in the breeze caused by the air conditioner. 

"This won't do!" She orders the director to take care of the problem. He assures her that he will take care of it, if she'll just wait in the outer office for ten minutes. 

She leaves and comes back after exactly 600 seconds. Sure enough, her husband's hair is all in place.

A month later, the widow is reviewing the bill for the funeral and she notices there was no charge for the hair problem. She calls to inquire as to why. She's told that it was "on the house." "Nonsense," she retorts, "you expended time and materials and I will compensate you for it. Now, give me a price!"

"Ok, madam", the funeral director wearily agrees. He holds the phone away and hollers across the room, "Hey, Charlie, how much did that nail cost to put that toupee in place last month?"
