So, there I was, binge-watching NCIS, you know, just another Tuesday night. I'd seen every episode a dozen times, but I was still trying to figure out if Gibbs was really that old, or if Mark Harmon just had that timeless face. Then it hit me, I didn't even know how old the rest of the team was when they started! I mean, sure, I knew Sean Murray was the baby of the group, but how young was he when he first stepped into that lab?

Now, I'm not one to go digging through Wikipedia like some kind of obsessed fan (okay, maybe I am), but I figured it was time to find out. Turns out, Sean Murray was just a kid when he started on NCIS! I mean, can you even? Let's rewind, shall we?

From Teenage Heartthrob to Forensic Scientist

Picture this: it's 1993, and a young Sean Murray is just 16 years old. He's not solving crimes or analyzing evidence, no, he's busy being a teenage heartthrob on Harts of the West. I know, right? I had to pick my jaw up off the floor too. But hey, we all start somewhere.

Fast forward to 2003, and Murray is all grown up (well, sort of - he was only 21), ready to take on the role of Timothy McGee in NCIS. I mean, can you believe they let a 21-year-old play a forensic scientist? Talk about starting young!

From New Kid on the Block to NCIS Veteran

Now, I know what you're thinking, "But how did he manage to pull off playing a grown-up when he was barely out of his teens?" Well, folks, that's the magic of Hollywood. And let's be real, Murray had the baby face down pat.

But seriously, Murray's been with NCIS since the beginning, and he's seen the team grow and change over the years. He's gone from the new kid on the block to an NCIS veteran, and I don't know about you, but I think he's done a pretty great job of it.

So, there you have it, folks. Sean Murray was just a baby when he started on NCIS. I know, I know, it's mind-blowing. But hey, at least now we know Gibbs isn't the only one who's been around since the dawn of time. Or maybe he is, and they just won't tell us.

Anyway, next time you're watching NCIS, remember to appreciate the youthful glow of Sean Murray. And if you're feeling really nostalgic, go rewatch Harts of the West. I won't judge. Much.
