Once upon a time there was an engineer
Drove a locomotive both far and near
Accompanied by a monkey that would sit on a stool
Watching everything the engineer would do
One day the engineer wanted a bite to eat,
He left the monkey sitting on the drivers seat,
The monkey pulled the throttle, the locomotive jumped the gun
And did 80 miles an hour down the mainline run

Big locomotive right on time, big locomotive coming down the line
Big locomotive no 99, left the engineer with a worried mind

The engineer called up the dispatcher on the phone,
To tell him all about his locomotive was gone
Dispatcher got on the wire, switch operator to the right,
Cause the monkeys got the main line sewed up tight
The switch operator got the message on time,
Said theres a northbound livin on the same main line,
Open up the switch Im gonna let him through the hole,
Cause the monkeys got the locomotive under control

Big locomotive right on time, big locomotive coming down the line
Big locomotive no 99, left the engineer with a worried mind
