Abrasive comic Don Rickles, the honorary Rat Pack member and celebrity roast guest whose career spanned six decades, has died. He was 90.

Rickles died Thursday morning at his home in Los Angeles from kidney failure, his longtime publicist Paul Shefrin confirmed. He would have turned 91 on May 8.

Though he appeared in films and on television, Rickles’ mainstay was always nightclub performances, appearing in Las Vegas and elsewhere into his late 80s. He also found late success as the voice of Mr. Potato Head in the “Toy Story” films, which were exceptional box office performers, and popped up frequently on latenight talkshows.
