The barn at Larry and Susan's farm burned down, and Susan called the insurance company. 

Susan said, "We had that barn insured for fifty thousand and I want my money."

The agent replied, "Whoa there just a minute, Susan, it doesn't work quite like that. We will ascertain the value of the old barn and provide you with a new one of comparable worth." 

Susan responded after a pause, "I'd like to cancel the policy on my husband."
