Yup, Larry Holmes was using Tex Cobb as a punching bag for 15 rounds, and Howie was so perturbed that the ref wouldn't stop the fight that he announced that he would never call another professional bout.
Cobb, when told about it in the locker room quipped, "Tell him I'll go another 15 rounds if he'll quit Monday Night Football too." One of the best impromptu lines ever....
