Don Rickles Dies at the Age of 90

Legendary comedian Don Rickles has died at the age of 90. Rickles died of kidney failure Thursday morning at his home in Los Angeles, according to his publicist.

His storied career spanned more than six decades. He was known as the "best insult comic" ever, and was known for making regular appearances on The Tonight Show and The Dean Martin Show. He frequently worked with Frank Sinatra, and became an honorary member of the "rat pack." 

90 years with Don Rickles weren't enough. One of the sweetest and most lovely people I had the pleasure of knowing. We miss you already
