So, I was at work moving around some stuff in the kitchen when I accidentally knocked over the fire extinguisher, causing the pin to fall out.
I asked my co-workers wtf I was suppose to do, but they aren't very helpful so I tried to put the pin back in myself.
I looked at the handle thing and saw two holes, big enough to fit the pin in. But he pin wouldn't fit because they weren't aligned.
So me with my infinite wisdom thought to myself, 'I'll just squeeze the handle and slip the pin in', causing the fire extinguisher to go off.
Luckily it was only Co2 so it just made a god awful noise instead of a mess.
