Would you ever the fire alarm to get out of class?

I got the idea for this question from today.
Here's the story.
Josh and Steven were just being boys and rough housing by the fire alarm, but they didn't know it was behind them. So Steven was in front of Josh and Josh faced his back to the alarm. Steven pushed Josh and his backpack pushed the switch in and down, setting it off! I screamed because I didn't know what happened until someone told me.


This one looks just like the ones in my school.


Have you/would you ever set one off??
