Larry King, 81, was one of the many celebrities who took to Twitter to pay tribute to "The Simpsons" co-creator Sam Simon, who recently passed away at the age of 59 after losing his battle with cancer.

"RIP Sam Simon. Your impact on television and the world will not be forgotten," the CNN's "Larry King Live" show host tweeted.

In a recent interview with "The Breakfast Club," King talked about death and religion. The atheist and veteran broadcaster pointed out that religion came into being because of the fear of death.

For King, death is the biggest fear humans have and "the only reason for religion is death."

"If you didn't die, there would be no religion," King said but clarified that he does respect almost every great religious leader.

Meanwhile, former WBO Champ Lamon Brewster, 41, recently revealed Simon was not only a writer and a philanthropist; he was also into boxing.

"Sam would spar with me to help me get ready for my fights," Brewster told TMZ Sports about his manager from 1999 to 2006.

Brewster was emotional about the death of Simon, especially because he was like a father to him. He said Simon was always giving him "life advice and cracking jokes."

"He could hit! He had a good heart, man and so down-to-earth," Brewster said about Simon. "Sam is now in a great place and I am pretty sure he is up there telling jokes."

In 2004, Brewster surprisingly won the vacant WBO heavyweight championship by knocking out Wladimir Klitschko in the fifth round to in Las Vegas. In 2006, he lost his WBO title to Sergei Liakhovich from Belarus by unanimous decision.
