It wasn't Gosselaar's first TV appearance, but it's the earliest one we could find on YouTube. ''I don't really remember anything about it except that I had a huge crush on Soleil Moon Frye,'' he says. ''We went on, I wouldn't call it a date, but there was this teen club that you could go to, and she invited me, and I thought that was the coolest thing. I was a very innocent, sheltered little kid, and she had been in the business for a while and been on a hit show and she was very seasoned for her age. I just was, like, wow. It would be the equivalent of me dating an older woman at 16. I couldn't believe that I was hanging out with Soleil Moon Frye.''
