Bill Cosby is celebrating his 82nd birthday today (July 12) behind bars. However, that hasn't stopped the fallen comedian from issuing some advice that many may deem ironic.

The comic-turned-convicted sex offender took to his social media accounts on Friday morning to urge "all men" to "man up & become men of valor."

"I would like to thank all of my friends, supporters and family members for wishing me a Happy 82nd Birthday," his post started.

It went on to claim that Cosby's fellow inmates at SCI Phoenix, a maximum-security prison in Pennsylvania, asked him, "Mr. Cosby – is there anything special you would like for your birthday?"

In response, he quoted one of his favorite Bible verses: "I politely replied that the greatest present for me is: 1 Corinthians 13:11 — When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things."

He concluded his post with a more direct message, dedicated "to all men."

"It's a time to be Great Fathers, Great American Citizens & Great Husbands. Man Up & Become Men of Valor," he wrote.

Cosby is currently serving a three-to-10-year sentence after being found guilty of drugging and sexually assaulting Andrea Constand at his home in 2004.
