Old-Timey Bubs
From Homestar Runner Wiki
The Old-Timey version of Bubs works at the Parsnip Depot. He has a stripe on his midsection and he owns a shop, just like his modern-day counterpart. He speaks with a very wheezy voice. It is doubtful that this version is as good at dancing as the current Bubs, because he's blind and only has one leg, but he can play the banjo.
He is presumably the son of Mark Grave and was apparently buried alive. Therefore, since the tombstone bears the legend "Unmarked Grave", it is possible that this is his name.
