Here's what I think should be included:
-Addressing the falling out between Shannen Doherty and the cast(and why is she back to being friends with Jennie Garth but she and Tori Spelling allegedly hate each other?)
-The return of Douglas Emerson(who played Scott Scanlon, David's dorky friend who accidentally shot himself in S2). Just have him return and mock himself and that his character's death that made him more popular.
-Will Jason Priestley and Gabrielle Carteris admit that Brandon and Andrea had underlying feelings and that their characters didn't get a fair shot on the show
-The Brenda/Dylan/Kelly triangle was one of the worst storylines since it divided fans
-Speaking of bad triangles, fans got really pissed when Kelly refused to choose between Brandon and Dylan in Season 5
-Shannen Doherty and Jennie Garth should do a parody sketch where they both show up in the same dress just like Brenda and Kelly did in Season 1's Spring Dance episode
-The actress who played Emily Valentine should definitely make an appearance...to scare the crap of everyone.
