Injury from an ass

At the fire station we have monitors hanging from the walls that alert us to an urgent situation. The monitor will inform us of the nature of the emergency, location and other pertinent information.

In the old days some of the codes used were pretty clever. For example

• "OTIS" meant elevator entrapment.
• "MRED" meant an injury due to a fall from a horse. (think about it)
  

Come on! You have to have some fun with fire and rescue.

Then, sadly, we became sophisticated and our clever codes were replaced by other less descriptive, meaningless numeric codes.

However, abbreviations ARE used as part of the description of the emergency and as it turns out, sometime said abbreviations are a more accurate, and clever, description of the event than spelling out the whole word. Take for example "Injury due to an assault". Why not just tell it like it is? "Injury due to an ass" as shown on the attached picture.

Seems fitting to me.
