Peter Lupus, best known for his role on the original TV series Mission: Impossible.
Lupus is also famous for being one of the first well-known actors to completely take it off for Playgirl; he appeared in the April 1974 edition.

There are still a few images of Lupus floating around out there in cyberspace; unfortunately I will not be posting any of those here (just do a Google image search with safe mode turned off).
Lupus has a handsome face, a nice smile, and a great body to boot. I'm not going to mention that he is also -- well, how shall I put this? -- (ooops!).
