Actually, sadly I don't remember Tori Spelling, or a lot of the moments you mention. (I think I do remember the concert tickets episodes, and the Zack-breaking-leg - at least I remember him in a hospital bed with his leg up in traction or something, I think. Oh, and the Zack/Lisa kiss too.)

See, Saved by the Bell was not hugely my thing - I was a bit young for at least the early episodes and in my mostly-black private school I guess it was less of a HOT THING than in other schools. But I did catch episodes here and there, either during the original run or in rerun. (For a while years back they were airing reruns on Saturday morning - back when I still watched Saturday morning cartoons because I was young and they DIDN'T SUCK.)
