I submit Al Smutko, a production staffer on two Star Trek series (TNG and Voyager).
I was in grad school when TNG premiered, and my roommates and I discovered his name in the end credits. Thinking that this guy had an awesome (and funny) name, we would cheer for him every week when we saw his name. Being weird and nerdy fans, we made up a fan club for him. I eventually got in touch with Mr. Smutko, and he and I became friends; he even took my wife and me on a tour of the Voyager set.
Michael Ironside. That name sounds as badass as the characters he plays (or used to play—I saw him in some true-crime TV show recently, and he’s really let himself go).

Yma Sumac was supposed to be a name of Incan origin, but a lot of people couldn’t help noticing that it’s “Amy Camus” backwards.
I’ve remarked several times that actor Khigh Dhiegh, who played Chinese agent Wo Fat on Hawaii Five-Oh, and Judge Dee in the TV movie Judge Dee and the Monastery Murders, as well as a host of other Chinese and Japanese characters in TV and movies, actually was Anglo-Egyptian-Sudanese, and was really named Kenneth Dickerson. His stage name was a fanciful phonetic spelling of his initials. (And he used other spelling variants, as well, sometimes using the middle name “Aix”, which I’d interpret as “K.X.D.”)
