Video of the Day: The Return of Zack Attack!

How awesome is this segment? Isn’t it weird to see Mark-Paul Gosselaar back in his Zack Morris ensemble talking on his Zack Morris phone? And the hair!!! If you don’t have time to watch the entire thing, fastforward for his performance with the Roots at the end. Now you can have “Friends Forever” stuck in your head for the rest of the day, too.
