Here's a great story about a baboon named Jack who not only worked for a railroad company, but also assisted some guy who thought he could jump between train cars and ended up legless.

After some time, and I swear I am not making this up, it is said that Jack learned to change the signals at the train yard. He responded to the horn blasts from the engineers and changed the signals accordingly. Locals swear that Jack never made an error. In fact, Cape Town train officials, after hearing of the monkey bidness up the road, came to investigate. Skeptical, they agreed to test Jack's competence and the little guy passed with flying colors. After he aced the signal exam, Jack was officially given a government salary (bananas?) and was issued an employee number. Really.
There are tributes to Jack the Signalman, as he was known, at the Albany Museum in Grahamstown (they have Jack's skull) and the Uitenhage Railway Station.
God bless that hard working monkey.
