Gaurav has tried to translate the famous attempt by Pu La of defining the traits of the people of the three cities,viz. Mumbai,Pune and Nagpur.
All this preparation should be enough to make you a normal Punekar. But if you want to operate a shop in Pune, you need more lessons. You especially need lessons on language. Only then will you be able to heap maximum insults on your customer in minimum possible words. Because in Pune, the verb "operating" a shop is used in the same sense as "operating a bull dozer" or "operating a machine gun". The most negligible entity in a shop in Pune, is the customer.
Read the entire post over here. And yes, if you know Marathi then do try to get hold of the recordings in the voice of Pu La. Hillarious, to say the least.
For the novices, you can read about Pu La more over here and here.
