Don Rickles, king of insult comedy, dies at 90

Paul Shefrin, his longtime publicist, said Rickles died of kidney failure at his home in Los Angeles.

Rickles and Frank Sinatra became friends and worked together many times over the years.

Rickles' fellow comedians and peers are clearly taking the loss hard, many of them mourning the comedy legend via social media. (The mid 1970s nautical sitcom CPO Sharkey barely ran for two years on NBC.) He appeared in films like the Toy Story franchise (voicing Mr. Potato Head), and did dramatic turns in John Landis' Innocent Blood and rubbed elbows with Robert De Niro and Joe Pesci in Martin Scorsese's Casino.

Rickles' career spanned more than a half-century.

The series, which lasted two seasons, centered on Rickles' highly abrasive character who oversaw a cast of seaman recruits for the navy. "I'm just stunned by this".

"It's a mistake", Rickles said upon accepting the prize (watch below). Rickles, who died Thursday at age 90, was among the most loved people in the business.

Rickles leaves behind his wife, two children and two grandchildren.

Tim Allen: "Don Rickles is one of the biggest reasons I am a comic today".

With Sinatra's endorsement, Rickles began his comedic assault on people famous and not so famous - Jews, Asians, African Americans, the Irish, Puerto Ricans, red-headed women, short guys, you name it - with tremendous results.

Rickles returned for "Toy Story 2" in 1999 and "Toy Story 3" in 2010, though it's now unclear if he had recorded his voice work for "Toy Story 4" (due out in 2019) before his death. I'm supposed to be doing comedy.

He often made appearances on late-night talk shows and was known for roasting celebrities.

Rickles was born in New York City on May 8, 1926.

"The customers were right on top of you, always heckling, and I gave it right back to them", he recalled in 1982. "One of the sweetest and most lovely people I had the pleasure of knowing."- Jimmy Kimmel via Twitter.

Patton Oswalt joked on Twitter: "In lieu of flowers, Don Rickles' family has requested that people drop their trousers and fire a rocket". Rickles guest-starred in Get Smart as Sid, an old war buddy of Max who comes to stay with him.
