Dollar on Top

A father concerned about his software engineer son's geek-ish mentality decided to talk to him on the importance of financial matters in life and posed him a simple question - "Son - for all the knowledge you have - do you know why the dollar is on top of the rupee these days?"

Pat came the reply from the son: "Yes Dad, blame the keyboard manufacturers - on the keyboard, the dollar ($) sign is always on top of the Rupee (R) !"
