Talk:The Spirits of '76 Back to page 7,959pages on this wiki Edit History Mr. Grumper "Grumper" is not his proper name as far as I can tell. It seems to be a nickname Shaggy came up with. Is there evidence otherwise? Also he is never seen mopping and he's a security guard, not a janitor. Retrieved from "http://scoobydoo.wikia.com/wiki/Talk:The_Spirits_of_%2776?oldid=55459"
