Tiffani Thiessen remains the only “Saved by the Bell” cast member who hasn’t signed on for a reunion on Jimmy Fallon’s “Late Night” show, and she made a joke-y video for Funny or Die (see below) to explain why she’s too busy to do it. Apparently she’s making cat videos and helping NASA and some other whimsical things that I didn’t find very funny. It’s obviously supposed to show that she has a sense of humor about the situation, but it fails because if she had a sense of humor about it, she’d just go and do the stupid reunion. Dammit, Tiffani, an entire generation of Americans had to shut their brains off to like that retarded-ass show, the least you could do is indulge in our nostalgia. Who do you think you are? Jennie Garth?
