Okay, let’s be real for a second. We’ve all done it: thrown on some Ed Hardy, cranked up “Get Low,” and re-lived the glorious, chaotic, hair-gelled wonder that was Jersey Shore. But as you watch Snooki get punched in the face or Ronnie smash a room, a question inevitably bubbles up like a grenade on the boardwalk: How old were these beautiful disasters?

Grab your GTL schedule, because the answers might shock you. When Season 1 hit MTV in December 2009, the cast was basically a bunch of babies in club clothes. Nicole “Snooki” Polizzi was the baby of the bunch at just 21 years old. Can you imagine being 21 and having a meatball as a life title? Then we have our guidos: Mike “The Situation” Sorrentino was 27, while Paul “DJ Pauly D” DelVecchio was the old man of the crew at 29. That’s right—the guy with the blowout and the roided-out abs was almost thirty, spraying tan like he was running from Father Time.

The rest? Jenni “JWOWW” Farley was 23, Sammi “Sweetheart” Giancola was 22, and Ronnie Ortiz-Magro was the same age. Vinny Guadagnino—the thinking man’s guido—was a fresh 21. And Deena Nicole Cortese? She joined in Season 3 at just 23. So basically, most of them were college-age adults acting like they were on a permanent spring break. It’s honestly a miracle they all survived, considering their biggest life decisions involved “did I apply enough hairspray?”

Now, here’s the uplifting part. Look at them today. Most of them have grown up—they’ve got kids, businesses, sober lives, and actual sense. The babies of the boardwalk became bosses. So next time you see a twenty-something acting a mess, just smile. Time, like a perfectly windblown pouf, always finds a way to settle down. The shore might have been wild, but it gave us a lesson: you can start as a grenade and still end up a diamond.
