Jimmy Fallon scored a Zack attack on his show last night, with Mark-Paul Gosselaar making a full appearance as Saved by the Bell heartthrob Zack Morris (and his sweet cell phone). Eat your heart out, Kelly Kapowski.

Side note: The top two google image search results for Kelly Kapowski are Tiffani-Amber Thiessen in jeans and a tube top bra. In the second one, she’s wearing suspenders. What, no nipple?
