Happy birthday, MPG! Mark-Paul Gosselaar turns 39 today, and it's hard to believe that the Saved by the Bell heartthrob — who's just as hot as ever on Franklin and Bash — is nearing 40. Kelly Kapowski wasn't the only one smitten with Zack Morris. I would have called him on that oversize cell phone if only I had the number. If you (or your friends) had a thing for MPG's Bayside High alter ego, these fun, nostalgic gifts will give you a Zack Attack!
