The Demon
From Homestar Runner Wiki
The Demon makes a cameo appearance in an Easter egg from Parsnips-A-Plenty. In it, he's in Hell, poking Old-Timey Strong Bad with a pitchfork. His appearance, tool action, gloves, and relation to The Kaiser (who is the Old-Timey version of The King of Town) have lead many to believe he is the Old-Timey incarnation of The Poopsmith. This interview with Matt Chapman validates this to some extent.
