Let me tell you a li'l bit about Bihar. That it's not the same as Uttar Pradesh, UP, or Oo-Pee, as natives pronounce it. Or "UP-Bihar", as Bombaywallahs love to club-sandwich it, while they've encountered very few Biharis, in fact.

It appears to me that sometime in the '70s, there were two trains simultaneously starting from Bihar and UP, heading for Bombay and Calcutta. And between each other, the two states had to pick one train. Biharis chose Calcutta. UP-ites betted on Bombay. Don't need to underline who made the better choice.
