I once heard a story about a railroad crew that befriended a monkey named Bobo.
The railroaders would play with Bobo and feed him and really treat him nice. In fact, they taught the monkey to give hand signals and run the engine and to even read a switch list and switch out the cars.
Soon Bobo got to be so good at it that the guys would let the monkey do their work while they went fishing. One day the Trainmaster caught the guys fishing while Bobo was doing the work. All of the railroaders got fired on the spot.
A couple of months later the railroaders got a letter from the company. It was a great flowery piece and reinstated all of the railroaders to their former positions with all back pay. It was signed by Trainmaster Bobo.
