Actor Richard Dunn, best known for playing a bizarre Charlie Rose-like version of himself on the Adult Swim show Tim and Eric Awesome Show, Great Job! has passed away, according to a tweet from Tim and Eric‘s Tim Heidecker.

In recent years Dunn racked up numerous credits playing variations of the doddering old man type, with small parts in Parks and Recreation, Weeds, The Wedding Singer and the music video for P. Diddy’s “Bad Boy for Life.”

In a 2007 interview with The Onion A.V. Club, Heidecker and Eric Wareheim described meeting Dunn:

EW: We were looking for Tim’s dad for the first episode of Awesome Show; we wanted it to be a much older guy, as if Tim hired some old guy to pretend to be his dad. Richard was just this old guy with funny glasses and an older sweater.

TH: We actually saw him from our office, in the parking lot, getting out of his car, smoking a cigarette. He was wearing that sweater… It was immediate to us. We looked at each other and jumped up and down. Then once he started talking, it was unbelievable.
