interesting story about a dead battery

[ticopowell]

So my battery died the other day because I left my flashers on, and so I had a guy come and jump my truck (yes i used the proper jumping technique). While I turned the ignition key to start it the guy disconnected the cable from the truck. I assume he did this to make sure there was a good connection. I jumped out to see what he was doing and why he did that. before I jumped out I turned the truck off all the way, but when he tried to reconnect the cable the engine started turning over. we all kinda say wtf was that, so i grabbed my keys out of the truck completely and it did it again. so i then put the keys in, turned them to start the truck while the guy connected the cables again, and the truck started right up.
Anyone heard of something like that happening before?
