Sardar Jokes are very common in India. They are the equivalent of Blonde Jokes in the United States.
Wikipedia states, "Many of the Sardarji jokes are variations of other ethnic jokes or stereotype jokes. Some of them also depict Sardarjis as witty. Researcher Jawaharlal Handoo associates some traits of the Sardarji jokes with the stereotype of Sikhs being associated with jobs where physical fitness is more important than knowledge of the English language or intellect.
Although such jokes have come under criticism from the Sikh community, it was said that the jokes were best said by Sardar's themselves presenting Khushwant Singh as an example . As Vir Sanghvi writes, "The Sardarji joke, like all ethnic humour, is part of a good-natured Indian tradition and hardly an example of any kind of anti-minority feeling."
I received a couple of great Sardar jokes in the mail and couldn't resist posting them. For the record, I obviously don't see any merit in the claim that Sardar's are of low intellect and whatnot. I have known many of them who are intelligent and confident people.
Here are a few:
A Teacher lecturing on population - "In India after every 10 seconds a women gives birth to a kid."
A Sardar stands up- "We must find her and stop her!."
Teacher: "I killed a person" convert this sentence into future tense.
Sardar: The future tense is "You will go to jail".
A Sardarji is travelling for the first time in a plane, headed for Bombay. While the plane is landing, he starts shouting "Bombay, Bombay!".
The air hostess says, "Be silent".
Sardaji says, "OK", and starts shouting "ombay, ombay".
