Mario Lopez, aka A.C. Slater of "Saved by the Bell" fame, will be at the Mall of America to sign his new workout book, "Mario Lopez's Knockout Fitness."

The book boasts a "diverse exercise regimen that brings together sweat, discipline and excitement to help readers achieve the best body possible in six weeks" -- apparently like Lopez's rippling shirtless torso on the book's cover. Bonus: color photographs of "Mario exercising with his celebrity friends." I'm so in!
