Trying to decode the many variations of the head bobble.
Figuring out what grammatically bizarre "Indianisms" actually mean.
Marveling at how creamy, delicious kulfi manages to stay so cold in summer.
That's probably what the 17 million tourists to India wonder each year as they flock to the country of 1.2 billion people.
Just for them, here's a list of ways India outshines the rest of the world.
In India, a simple hair cut is anything but.
Barbers will take their scissors to wayward eyebrows, tufts of ear hair and nostrils.
That's just the beginning.
Once the customer is shorn, wet-wiped and toweled off, barbers begin a firm head, neck and shoulder massage, which can descend into facial slapping and skull-pounding known as "champi," which is where the word "shampoo" comes from.
Be warned: their signature move is a swift neck crack, which can come as a shock to first-timers.
2. Enterprising street vendors
India's street vendors sell the usual wares, from fake DVDs to earrings to bags of masala popcorn and roasted peanuts.
But there's also ear-cleaning, street dentistry and pavement astrology.
Vendors possessing the presence of mind to seize any opportunity -- last year when Starbucks opened in Mumbai, the queues were so long, a tea-vendor set up shop outside and sold his wares to waiting customers.
3. Old world train travel
This year marks 160 years since the birth of Indian Railways, which carries more than 20 million passengers a day along 65,000 kilometers of track.
Thundering through cities, inching past villages, snaking along coastlines and climbing mountains, the network of toy trains, luxury trains, Shatabdi speed trains and commuter trains is lovingly known as "the lifeline of a nation."
In terms of safety, however, there's still far to go, owing to the trains' decrepit state, unmanned crossings and lack of government attention.
Tip: travelers should choose the new derailment-proof Duronto trains -- there's no better way to see the country.
4. Notorious celebrities
Hollywood stars have nothing on Bollywood stars when it comes to entourages, paparazzi and fanatic followings.
They might endorse skin-lightening creams, produce terrible films and become embroiled in one scandal after another, but almost nothing can't dim their stardom.
Current fave Sunny Leone -- a former pediatric nurse trainee in Orange Country turned porn star and now mainstream actress -- is the most searched celebrity on the Internet, racking up 35 million searches in India this year.
