Say it ain’t so, Gandhi! What he actually said, according to The New York Times: “If we could change ourselves, the tendencies in the world would also change. As a man changes his own nature, so does the attitude of the world change towards him…We need not wait to see what others do.”That’s a lot longer though.
"That's
one
small
step
for man,"
...and then changes in the second part when he realizes he missed the "a"...
"one
giant leap
for mankind."
It doesn't matter what he meant to say, just what he did say. If he had tripped and said, "Fuck!", that would have been the first word spoken by somebody standing on the moon.
