A majority of the Saved by the Bell cast boarded a surreal time machine last night to visit Jimmy Fallon in L.A. Everybody briefly (re-)enrolled at Bayside High for a sketch about a school dance — and the fact that Fallon’s coming back to New York City soon. It was all a little too self-reflexive. But it was a treat to see Mark-Paul Gosselaar, Mario Lopez, Dennis Haskins, Elizabeth Berkley, and Tiffani Thiessen all on the same set again after more than 25 years. Also, Fallon mentions his Nicole Kidman video-games-and-Brie blind date, which will always be fun to revisit.
