Johnny Hardwick, the voice actor for the iconic King of the Hill character Dale Gribble, has passed away at the age of 64. The news was announced in a joint statement by 20th Television Animation and Hulu.

According to TMZ, law enforcement sources said they were called to Hardwick's Texas home on Tuesday for a welfare check and then found his body. No foul play is suspected, and the exact cause of death remains unknown.

News of Hardwick's passing led to a celebration of some of Dale Gribble's greatest moments from King of the Hill. Dale had several classic moments as Hank Hill's conspiracy-minded friend on the show, several of which led to enduring memes, including Pocket Sand and Are Y'all With The Cult?

Many on social media joked they would toss "pocket sand" in Hardwick's honor, while several joked they would honor the memory of "Rusty Shackleford," an alias Dale used to try and hide his identity.
