St. Louis woman Michelle White was sentenced to 15 years behind bars Friday for sticking up a White Castle hamburger joint with a water pistol.

Prosecutors said the 33-year-old drove to the restaurant and handed a threatening note to an employee while brandishing a water pistol, according to KWGN-TV.

When the employees fled to the back of the restaurant, White shimmied through the drive-thru window and stole more than $600, according to Assistant Circuit Attorney Melissa Giliam.

A witness to the crime took down White's license plate and called police. They soon converged on White's home and she reacted by climbing onto the roof and leaping, fracturing an arm, a leg and her pelvis in the process.
