The 73-year-old former football star took to Twitter ahead of the weekend to deliver his two cents about the disgraced actor being denied parole.
According to the parole board, the 83-year-old Cosby Show star has refused to participate in a required treatment program for "sex offenders and violence prevention.”
O.J. -- who spend some time in prison -- addressed the news on Twitter and shook his finger in Cosby's direction.
"Bill Cosby decided not to take a court-ordered sexual course in prison and it probably cost him his parole so he's not getting out," the ex-NFL player told his followers on Friday.
In 2018, Cosby was sentenced to three to 10 years in state prison after being found guilty of raping former Temple University employee Andrea Constand in 2004.
O.J. isn't impressed with Cosby's decision not to partake in the program, revealing he did anything he could to get out of prison.
"When I was in camp [prison], I took anything!" he said.
"[I took] all the courses. I wanted to get home to my kids," O.J. continued, before revealing he took a victim impact course during his 9-years behind bars.
Saying the course was "particularly galling," Simpson explained, before getting salty while explaining exactly what the course entailed.
"I had to get up and apologize to my victims and I got up and said, 'Guys, I'm sorry I caught you trying to sell my stolen property. I'm sorry I yelled at you and I'm sorry that the state of California ruled it was my property, gave it back to me, and you didn't make any money off my stolen property,'" he told his fans.
Turning the focus back on Bill Cosby, O.J. said, "I would have taken anything to get home and get out of prison."
In 2008, O.J. was sentenced to 33 years after being found guilty of a kidnapping charge, and mandatory prison time for armed robbery.
He was released in October 2017 after serving just 9 years.
