I have the world's best water pump story. About 45 years ago, I was working in a Sears garage. After my shift, I was walking out to the employee parking area. I happened to walk past a car juss as a fellow employee was starting it and heard a very distinctive "twannnggggg" as the engine reved up. I motion for her to shut it off and I popped the hood (I still had my mechanic work clothes on). I grab the fan and gave it a wiggle and then I walked over to her window and said, "You need a new water pump." The look on her face was priceless !!
