 Gumbys stand stoop-shouldered, with their hands permanently clenched in front of them, elbows slightly bent, and their feet turned to the outside.They wear folded white handkerchiefs knotted at the corners on their heads, which supposedly is what gives them their limited intelligence (as it sometimes has happened that they are more normal until they put them on), and have toothbrush moustaches.Their most famous catchphrases are "My brain hurts!"
