Boy Ed that reminds me of one. I went on a trouble call on an 756 PBX (hotel motel) when I got there, there were relay caps everywhere. I asked the manager what happened and he said he just pulled out the rack door and slammed it back shut to try to clear the trouble, as he had seen one of the "techs" do many times. Don't know how many of you have ever seen a large X-bar switch with literally hundreds of flipped wire springs on relays. Oh what fun, I was there for hours. I put the pins in all the doors, very tight, when I left.
