Hey, hey, hey... who let Fat Albert back on social media?

Bill Cosby’s official social media accounts sent out a surprising Father’s Day message late Sunday while the actor-comedian is in prison.

“Hey, Hey, Hey...It’s America’s Dad...I know it’s late, but to all of the Dads... It’s an honor to be called a Father, so let’s make today a renewed oath to fulfilling our purpose — strengthening our families and communities," @BillCosby wrote on Twitter, Facebook and Instagram with the hashtags #HappyFathersDay and #AmericasFavoriteDad.

Cosby’s spokesman, Andrew Wyatt, confirmed to USA Today that the message was from Cosby himself in support of a group called Man Up.

“Mr. Cosby’s (message) consisted of telling these men who have been incarcerated for many years, but are up for parole soon...to...take the word ‘disadvantage’ and remove the ‘dis,’ and start focusing on the advantage,” Wyatt said. “That advantage is to be better fathers and productive citizens.”

Cosby is currently serving a sentence of three to 10 years in a Pennsylvania prison after being convicted last year of drugging and sexually assaulting Andrea Constand at his home near Philadelphia in 2004. Cosby was previously accused of using quaaludes to drug and rape dozens of other women and had settled a civil lawsuit with Constand for $3.4 million before the case was reopened.

Cosby was previously known as “America’s Dad” for his role as Dr. Cliff Huxtable on the top-rated “The Cosby Show” from 1984 to 1992. Cosby’s credits also included “Fat Albert,” “I Spy," “Ghost Dad,” “The Electric Company” and several standup comedy albums.
