Does half of a cuss word count?

I had an interesting situation today. All was well as my 26 students were cleaning the shop. Suddenly a familiar scent came upon me that smelled like natural gas. The students began to argue that the smell was the cleaning fluid. Looking towards where the smell was coming from was a gas heater. I then realized that since it was a cool day the heater had started. The only problem was there was not a flame. The smell became stronger so I told the students to exit the building. Students were still looking on and offering advice like should we open more bay doors. I emphatically insisted they leave and not bother with the doors since they might provide a spark to finish us off. The students still insisted upon staying and defying my orders. I thought for a moment that they might have become brain damaged from the smell, but since I was much older and still had my senses I figured they were still adolescents. Suddenly I said the half cuss word that started with that special letter. I shouted "get the ## out of the building." I really did stop in the middle of the word. I am pretty sure they knew what I meant since they left the building. Tomorrow is another day!!
