He’s known for playing all-American high school heart throb Zack Morris on Saved By the Bell.

But it turns out Mark-Paul Gosselaar was a lot edgier than we imagined. The actor appeared on the George Lopez show last night where he revealed that as a teenager, he used to smoke pot with his mother.

“So being Dutch, they’re very liberal when it comes to herbal …” said Lopez.

“Yeah, they like to get high,” said Gosselaar. “When you’re in Holland or Amsterdam… you go to a hash bar, order your coffee… I think the the last time I was in Amsterdam, I was 18 with my mother and we got high together. She’ll deny it, but she got f*cked up!”

What would Kelly Kapowski say???
