[post_page_title]Hairy face[/post_page_title]
Herbert Viola was often seen with a fair amount of stubble on his face. While this was a deliberate decision made by the show’s creators, the actor playing Herbert, Curtis Armstrong, liked to have some fun with continuity. He would regularly shave his face clean during shooting which resulted in several scenes in which Herbert would be without his customary stubble. He did this because the showrunners would joke his facial hair grew so quickly no-one would notice, which became an in-joke between the actor and the crew.
