This is the guy I always think of. He was in Weird Science, One Flew Over the Cukoo's Nest, The Hills Have Eyes (original) and about 200 other horror movies (and I think he was the principal in Motley Crue's Smokin' in the Boys Room video). Suffers from hypohidrotic ectodermal dysplasia, where extrusions of the body -- hair, teeth, and fingernails -- are unable to form. http://www.nndb.com/people/968/000026890/13835.gif Personally, I think Mench kind of looks like Sloth from The Goonies: http://www.ilovetheworld.co.uk/images/goonies.jpg
