Part of my childhood was watching (much to the dismay of my father who hated the 1960's sitcoms) "Hogan's Heroes." I liked Larry Hovis the best of the lot for his general state of confusion and ineptness combined with a flair for explosive ordnance.
Dawson's real name was Colin Lionel Emm (why is it that entertainers so frequently reject their given names?) and he is said to have introduced Bob Crane to his eventual murderer. Funny how things work out.
