The Twin Cities bar scene has seen its fair share of nostalgic '80s- and '90s-themed parties lately. (Aren't you glad you kept that acid-washed jean jacket?) Next up: The Shout House's "Saved by the Bell" costume contest this Wednesday in downtown Minneapolis. The dueling pianos bar has pulled out all the stops by hiring none other than Mr. Belding himself, Dennis Haskins, to host the party. Mr. Belding, if you've forgotten, was Bayside High's affable principal on "Saved by the Bell." So what's become of our dear Mr. Belding, you ask? Not much. However, he has found a second life on the karaoke circuit (search YouTube for evidence). He recently released a karaoke album called "Karaoke With Your Favorite Principal." Glorious.
