Paul Heyman has announced on his official website that "The Angry Grandpa" has sadly passed following a battle with several health issues. For those that don't know "The Angry Grandpa" started out on Heyman Hustle before moving to its own YouTube Channel.

Below is the official announcement:

"It is with heavy hearts that we at The Heyman Hustle announce the passing of a true YouTube pioneer. Charles Green, born October 16, 1950 and better known around the world as “The Angry Grandpa” passed away after battling several health issues over the past few months. The Pissed Off Patriarch became a viral sensation after debuting “The Angry Grandpa Show” right here on the Hustle.

Angry Grandpa‘s youngest son, “Pickleboy” is better known to long time readers of the Hustle as Michael 24/7, and was the Hustle’s original web designer and developer. Shortly after launching “The Angry Grandpa Show” the series became a worldwide phenomenon, as clips of Angry Grandpa losing his cool and tearing things apart started to be featured and fiercely debated on HLN’s Dr. Drew … TruTV’s Most Shocking … Rude Tube … and MTV’s Pranked.

“The Angry Grandpa Show” moved to YouTube, where the channel dedicated to Grandpa‘s antics and interaction with Pickleboy aka Kid Behind a Camera aka Michael 24/7 and Michael’s girlfriend Bridgette West amassed over 3 million subscribers and was well on its way to a billion views. This spawned the launched of Michael’s own Kid Behind a Camera channel, with 1.9 million subscribers and Grandpa’s Corner, which was an almost out-of-character personal channel where Grandpa would stories about his life along with a special weekly segment called “Mailbag Monday” where he would open packages and read letters sent in by viewers, whom he lovingly referred to as his “youngin’s.”
