Jimmy Fallon is trying to stage a Saved by the Bell twenty year reunion on his show. Recently Mark-Paul Gosselaar showed up on Late Night in character as Zack Morris. The idea is that Zack Morris is a real person and Mark-Paul Gosselaar is just a stage name since there was already a ZM in SAG.
Gosselaar Morris is up for a reunion as are Mr. Belding (portrayed by Dennis Haskins) and Slater (Extra's Mario López). The only reported holdout is Kelly (Tiffani Thiessen). Something tells me Screech (Dustin Diamond), Lisa Turtle (Lark Voorhies) and Jessie (Elizabeth Berkley) won't turn this one down.
