11. His Feuds With Joan and John
The feuding hardly ended with Newton and Snyder. In 1986, Joan Rivers started hosting her own show in direct competition with The Tonight Show. Prior to that, Rivers had been a repeat guest on Carson’s show. Once she got her show, Carson stopped talking to her. Another repeat guest was John Davidson, who later hosted the show “That’s Incredible!” He too became persona non grata after getting his own show. Davidson, however, did not share Joan Rivers’ intimate past with Johnny.
