Garth and his wife Sadie are having dinner

 

Sadie asks, “And who was that, another of your ‘girls’?”

Garth replies, “No, that’s Harry’s mistress.”

“You mean that Harry also has a mistress?” says Sadie, surprised.

Garth answers, “Of course, she’s been with him for nearly twelve years.”

Sadie then says, proudly, “I like ours a lot better.”
