OK here's what I think. Grunkle Stan might be a werewolf beacause on tourist trapped he went into the vending machine. He might have did that beacause he didn't want to damage anything and it was a full moon that night. Also on Dipper versus manlieness when Mabel was shaving Grunkle Stan his hair kept growing back.
