Yeah well all the Hogan's Heroes fans on my FL remember when Newkirk did his Bogart, Lorre, & Greenstreet impersonations. Well I just found a video of Dawson on The Diana Dors (that's his first wife) show doing about 14 different impersonations in a row. It's a really a lot of fun to watch so I am sharing. :)
