im not sure how the fire alarm tigger is in the US but in switzerland its a button with a small plastic case in fornt of it
5 years back one time at lunch (like mot lunch times) i was chillin with a buddy by the vending machine, and i was playing around and touching the plastic case surrounding it and joking that i would break it
i was flicking it and then, out of nowwhere, pops my libyan friend (only arab in school), he tell's me
"that not how you break it" and then proceds to nuckle the shit out that plastic case, of course the case breaks
there was then about 2 sec of pure silence, and then off goes the fire alarm, never and i mean NEVER have me and my friend laughed so hard (my libyan friend literraly went turned a KKK white, i guess the reality of it all just hit him)
i laughed so hard i was on the floor crying when the fire department arrived, i questionned him after and asked him why he did it, turns out he has no idea, was kind of a on the moment action
