Ring a bell? A Saved by the Bell?
The Pointer Sisters' tune, you'll recall, was the pivotal song Berkley's perfectionist Goody Two–shoes character, Jessie Spano, sings when she develops a one-episode addiction to caffeine pills. We all remember how well that ended.
Thankfully, buddy Zack is there to intervene and put her back on the right track. What would we do without Zack Morris and his giant cell phone, anyway?
Sadly, Zack, won't be there to help Berkley conquer the moves on the DWTS stage, but her dance partner Val Chmerkovskiy will. We're rooting for you, Jessie! (E!)
