A bald little Indian dude who just so happened to be one of the most evolved souls the world has ever known.
He was famous for his practice of non-violence by which he won India's independence from the British Empire without a shot. (You tell me of any other revolution that has been so successful.) Non-violence ("ahimsa") is basically the doctrine of not being a dickweed. This applies not only to humans but to animals and plants--literally "all living things". Gandhi was a fruitarian
, although later in life he ashamedly reverted to drinking goats' milk due to an attack of dysentery. (Go figure, they hadn't yet invented soymilk 100 years ago.)
Was killed because his progressive ideas didn't sit well with a certain moronic faction. And I must correct the poster who said he was killed by a Muslim. He was killed by a Hindu. Yes, even though Gandhi himself was a Hindu, he was killed by his own kin because they feared Gandhi's posture of universal tolerance toward Muslims. Just goes to show you that moronism supercedes religious affiliation. Morons are universal.
Other notable acheivement:
Popularized those cool "John Lennon glasses" long before John Lennon was even born.
Contemporary uses of the term "Gandhi":
Any time you can quote Gandhi, you win. Hands down.
MOM: What were you doing out all night? Getting high, I suppose? You & your hoodlum friends are nothing but trouble!
KID: Well, you know what Gandhi said, "The greatness of any nation can be judged by how well it treats its animals."
KID: You wouldn't understand.
