I was on "Blossom" from the age of 14 to 19 and we had some very famous guest stars, some of them before they were famous and others who were already well known.

We had Stephen Dorff, Tobey Maguire... Johnny Galecki even appeared on "Blossom" and we shared the 2nd kiss of my life together. Both of those kisses happened on "Blossom" and we were both around fourteen then.
