Steve Martin Syndrome (Condition) Describes someone with the unfortunate condition in which he looks 50 when he's 28, but fortunately, still looks 50 when he's 75. In other words, a person who perpetually looks 50.

You know it's a slow news day around here when we're resorting to birthday shout-outs, but this one is special, if only because, if you're like me, you will be floored to learn John Slattery's real age. Also: Let's be honest, who doesn't want an excuse to feature pics of this piece of tail from "Mad Men." Anyway, I'm not sure when I first saw John Slattery -- probably around eight years ago in "Ed" or "Sex and the City," but the dude has always looked 50 years old. And you get the feeling, he's probably got Steve Martin Snydrome. Or you would, anyway, if you realized that today he merely turns 45, making him the oldest looking 45 year old in Hollywood. Also, the best looking 45 year old in Hollywood.

And here's a couple of pics of Slattery, and because I'm feeling generous, a couple of his co-star on "Mad Men," Christina Hendricks, who makes my knees weak.
