Everyone should know who Zack Morris and Kelly Kapowski are. I used to watch Saved By The Bell every morning before school. 

It aired between my elementary and middle school days until I switched over to Boy meets World, which is another staple of my younger years. I know they both continued acting in things like Law & Order and BASEketball

The pictures below show a timeline of their relationship inside and outside of the show, which is crazy if you think that these characters were played by real people. I mean there's even a wedding picture in there somewhere! 



An interesting fact is that Lark Voorhies, aka Lisa, was Mark-Paul Gosselaar's real-life girlfriend throughout most of the filming of the show (3 years).
