Zack Morris himself made an appearance on Late Night with Jimmy Fallon Monday night. Startlingly unaged and sporting his signature preppy blond haircut, the "Saved by the Bell" star stayed in character for the entire segment.
"I'm Zack Morris. After school I became an actor," he told Fallon. "I had to change my name to Mark-Paul Gosselaar because there was already a Zack Morris in SAG."
Morris did several "time-outs," freezing Fallon and The Roots while he talked to the camera, and answered a call from Jessie Spano, who agreed to Mr. Belding's pleas to do a Bayside High class reunion on the show. Sadly, he also reported that he and Kelly Kapowski got divorced.
