24-year-old Sharonda Cheeves and 23-year-old Jesslyn Williams of Philadelphia are in prison . . . for getting revenge on a nightclub that kicked them out.

On September 4th, 2010, they went to a gay and lesbian dance party at a place called Club Motivation, but got thrown out for being drunk and disorderly.  They punched the bouncer in the face, but that didn't satisfy their need for VENGEANCE.

So Jesslyn got behind the wheel of her Monte Carlo, and circled the block, running over customers on the SIDEWALK, as they were leaving the club.

She made THREE laps, hitting people each time.  Then Sharonda took the wheel and went for a FOURTH lap.  And this time, the person she hit was KILLED.  Combined, they hit six people on their four laps, injuring five and killing one.

Last Thursday, a judge sentenced Sharonda to four-to-eight years and a $1,000 fine.  Jesslyn got two-to-four years and a $2,000 fine.  (Philly.com)
