Years ago when I was an apprentice, we were working in an old shopping center. I was installing pipe along a baseboard area and I went to nail in a strap to hold the pipe. When I hit the nail, it didn't move. I told my boss about it, I wasn't sure why the nail wouldn't budge. He said that it must have been that old metal kick plate along the wall and he wanted me to give the hammer a good wack and drive that nail home. Well wouldn't you know that the reason the nail wasn't moving was that there was a water pipe right behind the wall and when I hit that nail real hard, the water came spraying out like crazy. I tried to stop the water by putting my finger over the hole and I sceamed for the boss. Well after some time we found the water main, shut it off and had to repair the pipe before we could go home that day. BTW, we worked late that night and the boss use to call my "The Little Dutch boy" because I looked like I was trying to put my fingure in the dike to stop the leak.
