When I was about 16, I was walking through town one day. I saw John working on his truck, so I asked what he was doing. He told me he was rebuilding the transmission, and asked if I could help. "Sure,"He replied. We worked for a couple hours and got the whole thing put back together. We got in the truck and started up, and John put the truck in first gear. He eased his foot off the clutch... and the truck lurched backwards 4 feet!
John shut off the truck, looked at me and said, "Let that be a lesson to you, Lee. Whenever you test out a transmission, always look behind you first."
Lee finished the story, "I have no idea what that means, but I've never forgotten it, and I've tried to live my life by it."
A true story. All of which serves as an entrée to this video clip.
