Birthday presents

Mr. Benton thought he had had the last word when he presented his ex-wife with an unusual gift for her birthday. A tombstone on which he had carved, "Here lies my ex-wife Sonja.....cold as usual." Much to his surprise, however, his wife one-upped him for his birthday with a tombstone of his own on which she'd had carved, "Here lies my ex-husband Bennett.....stiff at last."
