The days of Saved by the Bell and seeing Mark-Paul Gosselaar in high tops, platinum highlights and… clothes(?!) are long gone! These days, Gosselaar’s making Zach Morris look like a “good boy.” After all, Zach never got caught with his pants down, did he?

However, Gosselaar has bared it all three times in recent years:

1. NYPD Blue. His first foray into on-screen nudity, audiences saw his bare buns
2. Weeds. Last summer, he rolled around in the covers with Mary Louise Parker in an episode of Weeds
3. Franklin & Bash. To emphasize his character’s womanizing ways, he’s baring it all rather frequently these days

PHOTOS: Forget Franklin & Bash – more True Blood scantily clad leading men!

But in a recent hot tub scene for Franklin & Bash, Gosselaar had the classic wardrobe malfunction!

“It’s top-stick. You literally just top-stick it to your thing, and that’s what you wear,” he told Billy Bush and Kit Hoover in an interview Access Hollywood last week – check out the video of the interview after the jump!  “That [was] a chlorinated hot tub, so it ate away the adhesive. So [during] take three, I stand up — and there [are] a hundred extras and the crew people [watching] – and, as [co-star] Breckin Meyer likes to say, it was ‘Screech, Slater and Mr. Belding,’!” he continued.

What I wouldn’t give to have been an extra… ((sighs))
