Harley's Punishment

As you were working the night shift, you couldn't help but notice Harley cutting a hole in the window in her usual manner, by smashing it to tiny pieces with a hammer. Your boss was too cheap for some method of contacting the police if such a thing happened, and so naturally, you panicked. However, today seemed to be lucky for you, as the bottom of the window was not completely gone. Harley, unable to see this, tripped over a portion of the glass still attached to the frame, and hit her head on one of your dispays. She knocked herself out.
