"Air India" joke

Santa was booked into an Air India flight to Bombay. But as this was his first time in an aeroplane, he made a few preparations that were out of place.
When the stewardess came around to take orders for the in-flight meal, Santa declared loudly, "I have brought my own lunch. Make sure you don't charge me for food and drinks!"
So, as everybody was given their in-flight meal, Santa began spreading out his own home-cooked meal. The man sitting next to him was an American history researcher and was curious about the food.
"Excuse me, what is that drink?" he asked.
Santa picked up the yogurt-based lassi drink and said, "Milk of India!"
Then Santa took out several pieces of chappatis and started feasting.
"And what is that dish?" asked the curious American.
"Wheat of India!" replied Santa proudly.
Finally, Santa took out some desserts. He offered some to the American.
"What is it?" asked the American.
"Sweets of India!" replied Santa.
After the meal, everyone was settling down when there was a loud 'Pooooooooot!' sound (fart) from Santa.
"What was that?" asked the American, holding his nose in disgust.
Santa replied coolly, "That's Air India."
