"Saved by the Bell" alum Tiffani Thiessen treated admirers of bubbly cheerleader Kelly Kapowski to an eyeful when she appeared in a sexy photo shoot earlier this week. And Mark-Paul Gosselaar (aka Zack Morris) further piqued nostalgia for the beloved '90s teen series recently when he said he'd be open to a "Saved by the Bell" reunion. But the character we miss most? That would be Mr. Belding, who had a relationship with Bayside's student body that was unconventional, to say the least (remember the time he blackmailed Zack into taking his niece on a date?). So, we're taking a look at Dennis Haskins, now and then.
