A a man in his 70's calls his son to tell him he and his mother are getting a divorce.
"Dad, you can't do this! You're not thinking straight." The son calls his sister to talk about it, and she is in agreement; their parents cannot do this.
"Dad, we're flying out there tomorrow. Do not sign any papers, contact any lawyers, or even thinking about going down to the court house."
After the dad gets off the phone, he looks over at his wife and says, "It worked. They'll be here for Christmas and are paying their own airfare."
