Bitty Bladder, after consuming her fifth vodka-tonic in less than an hour, needed to use the public restroom at Boogie Night Dance Hall. She was experiencing extreme discomfort, and was afraid of having an embarrassing accident, when she burst through the door of the ladies' restroom.

Much to Bitty's dismay, the only stall was closed with a sign that read: KEEP OUT. CLEANING IN PROGRESS. The cleaning woman, who was mopping the floor at the time, told Bitty, "I'm sorry, but you'll have to go to the other restroom." Bitty couldn't wait. "I'm going right here, right now!" she exclaimed.

The much smaller and older cleaning woman tried to block Bitty, a professional crocodile wrestler, from the stall to no avail. Bitty pushed her out of the way. The cleaning woman slipped and fell, hitting her head on the cold, wet tile floor. Bitty didn't skip a beat and promptly relieved herself.

Once done, Bitty opened the stall door only to see that the cleaning woman had not moved. Bitty immediately called for medical assistance. The medics pronounced the cleaning woman dead on the scene.

Bitty spoke to the officer investigating this death. She explained to him that she had bladder problems, and did not mean to kill or even hurt the cleaning woman. Bitty simply pushed the cleaning woman out of the way so that she could use the restroom. Bitty was arrested after giving her statement to the investigating officer.
