After college a bunch of my friends and I rented a house with a pool. One of my roommates had an old fire house from when he was a volunteer. One weekend evening we connected the hose to the fire hydrant in front of our house but it was too short to reach the pool around the back of the house , so we ended up running it in the front door and out the back door of the house . As soon as we turned on the hose the fire sirens went off in town (seems they had a low pressure sensor on the hydrant system). We continued filling the pool anyway and quickly disconnected every thing - man did it fill up quickly! We saw them the next day out checking all the fire hydrants. Luckily none of us had to go to jail!
