Joke da machaan-3

This joke was narrarted by a Finance professor who was training analysts from General Electric. He wanted to explain them a seemingly complex concept through a simple joke. My cousin who was one of the trainee's remembered the joke but didn't quite remember the concept :)

So this is third in the series- following my jokes about Michael Jackson and an Australian Army Captain.
