It's all right, cause I'm saved by the bell

I now officially love Mark-Paul Gosselaar.  Er, I mean Zack Morris.  
You see, Jimmy Fallon's been trying to organize a Saved by the Bell reunion, and Mark-Paul Gosselaar came onto the show to promote his latest venture, Raising the Bar on TNT, and also to pledge his commitment to a Saved By the Bell reunion.  But, the best part?  He does the entire thing totally in character as Zack Morris.
That's right.  He comes on as Zack Morris.  And then doesn't break character.  Not even once.
I love it when
