Seriously the best thing ever: Zack Morris was on "Late Night with Jimmy Fallon" last night -- yes, THE Zack Morris, not Mark-Paul Gosselaar.
Good news: He can still do "Time outs" and sings a mean cover of Zack Attack's #1 hit "Friends Forever."
The bad news: He and Kelly Kapowski got divorced.
Of Zack Morris!
