It was no secret that the late Ernest Borgnine and 3rd wife Ethel Merman did not get on. The marriage began unraveling on their honeymoon, and was dissolved after 32 days. In her 1978 biography, she devoted a chapter of her autobiography to the marriage: It consisted of one blank page.
Their mutual vitriol knew no bounds and with that in mind here's an alleged exchange between the two with some extremely NSFW language
Ethel Merman came back from an audition and said: "The director loved me. He said I had the body of a 16 year old and the face of a 21 year old."
Ernest replied: "What about your 60 year old cunt?"
Ethel retorted: "He didn't mention you."
