Months after refusing to reprise Bill Cosby for the 40th anniversary special of "Saturday Night Live" because he thought nothing was funny about the embattled comedian, Eddie Murphy had a change of heart and finally gave a blow on his much-awaited Cosby impersonation -- the first joke he has told in the last 28 years.

Washington Post reports that as the comedic hero received his Mark Twain Award Prize for American Humor on Sunday, he took the shot during his acceptance speech and it immediately burned down the house with laughs.

"Bill has one of these," Murphy said, referring to the Mark Twain bust he had received. "Did you all make Bill give his back? You know you f--ed up when they want you to give your trophies back."

Murphy had referenced allegations that there were some efforts rising up against Cosby, aiming for the 76-year-old comedian to be revoked with his Mark Twain award he received in 2009.

In his famous Cosby voice accompanied with a scorned facial expression, the funnyman continued to say: "I would like to talk to some of the people who feel like I should give back some of my f--kng trophies."

Murphy then on continued with a more pointed joke, this time involving fellow comedian Hannibal Buress who have brought Cosby allegations into the limelight during a stand-up comedy stint in 2014.

"You may have heard recently that I allegedly put the pill in the people's stomach," said Murphy in his Cosby voice. "Who is Hannibal Buress? First of all, Hannibal is a caveman's name. ... If I ever see or meet this Hannibal Buress in person I am going to try to kill this man!"

According to Los Angeles Times, Murphy's Cosby jokes can be considered "fairly tamed" as compared to Andy Samberg's stint at Emmy Awards and Amy Poehler's gig at the Golden Globe Awards.

Apart from the Bill Cosby impersonation, the 54-year-old comedian also cracked jokes, asking whether the Mark Twain recognition is a prize or an award. He quipped that he thought the award included some cash, but upon receiving, he warned future recipients that they will only get a surprise.

"When it's a prize, there's usually money involved," he said. "I thought I was going to get paper. . . . For future recipients, if you don't want to call it an award, you could call it a surprise - the surprise being you ain't getting any money."

Dozens of artists and friend flocked in the event to support Murphy's comedic genius including Chris Rock, Dave Chapelle and Arsenio Hall, as reported by The Hollywood Reporter.

The Mark Twain Award Prize for American Humor is given in honor of well-known writer and satirist, Samuel Clemens, famously known under the pen name Mark Twain.
