I don't know about these guys, but my marriage is great. We will never split up. I told my DH, "The only way your getting out of this marriage is through your own death."
And as I've told Mr. Inspectorette, "If you think I'd ever leave you and make you the happiest man on earth, you've got another think coming! I'm gonna stay right here and make you miserable" ;-)
Jack Benny had a line line in his comedy act years ago that went: "My wife Mary and I have been married for forty-seven years and not once have we had an argument serious enough to consider divorce; murder, yes, but divorce, never."
While Googling for the exact wording on that one, I came across two more classics by Benny:
"I don't deserve this award, but I have arthritis and I don't deserve that either."
"Give me golf clubs, fresh air and a beautiful partner, and you can keep the clubs and the fresh air."
