Homestar Runner's wacky lovable coach. We don't know exactly what he coaches. It's some weird sport played on a
football field, with a
basketball hoop, and some other weirdness.
That doesn't matter, anyway. Coach Z is really there to help out Homestar and his friends with fatherly advice when it's needed, much like South Park's Chef, but a little more G rated.
He's always there to congratulate Homestar on a "Jorb Well Done."
