6. Will Smith
Will Smith is one of those people who means completely different things to different people, depending on how old they are. For some people, they immediately think of Men in Black. For others, maybe I Am Legend or some of the other action movies he's been doing over the past few years. Maybe even Wild Wild West, but I feel really bad for you if that's the case. For me, Will Smith is and will always be the Fresh Prince of Bel Air. That's where he got his start, that's where he made his mark, and that's where he created the most catchy theme song in the history of television. Luckily for us, it's very easy to reconcile all of the different versions of Will Smith we have in our minds. Why? Because I genuinely do not believe that the man has ever aged. I have this theory that he popped into existence looking like the Fresh Prince, and he hasn't gotten any older. He's just been updating his clothes every few years, hoping that no one will notice. You can't fool me that easily, Will. I also have this other theory that involves the Tuck family and a secret stream of youth, but I thought that seemed a little far-fetched. Anyway, my point is, the man doesn't age, never has, never will.
