I was walking down the street with nothing to do, and this fixture standing onthe sidewalk said Pull for Fire I wanted to see a fire, so I opened it and pulled it the lever, wondering what would happen.. Nothing happened, so I strolled on.. I got about a block away, and four fire Engines with sirens blazing showed up, with all the men dressed their hats and uniform I got beaten for it, but really I didn't know what I was doing, and It said Pull for fire, so I did.
