Sometimes, a star has looked one way for such a long time, that you can't help but wonder if they were born that way. Did Danny DeVito ever have a full head of hair, or did his noggin gleam from even those first crowning moments? Did someone make a mistake and give George Burns the congratulatory cigar, rather than his dad? Or still, has Steve Martin's hair always been white?

The answer to the last: not at all! The above clip is from an episode of Sonny & Cher's Comedy Hour, and it shows Martin not only with a full head of bushy, brown hair, but also a mustache and beard. It's all-natural, 100% Grizzly Steve, in a too-short clip about air pollution. It's a nice little walk down memory lane -- one that's topped with Burt Reynolds trying to steal Teri Garr's purse... or maybe not quite. And added to that -- the clip ends with Sonny and Cher singing "I Got You Babe" -- well before she belted it out with Beavis and Butthead.
