Piledriver

In the Season 4 episode "Piledriver", Zorak beats Leonard Ghostal, the grandpa of Space Ghost, with a folding chair, complete with over-the-top wrestling commentary from Moltar and a cheering crowd. Space Ghost came back to see his grandpa knocked out, Zorak and Moltar tried lying by stating that Leonard fell down because of an accident, but that didn't work and while Space Ghost blasts a TV Monitor, Leonard Ghostal later got up from getting hit from a chair and fights back Zorak in a Wrestler-like move.
