Thread: A Question about a famous movie scene - 10 pts for best answer?

Does anybody knows this...?
you know that very famous westerns scene, that when a movie wants to make fun or a parody about a western they always uses that scene, it goes like this:
2 cowboys/gunmen, in the wild west, getting ready for a gun duel, they face each other, looking at each other, with their hands ready to grab their guns, and there are winds and sand is flowing, and then there's this 'roll of dirt' (dont know how its exactly called, its made of some light branches and some dirt, and it has the shape of a ball) rolling by in the background or between them, and while its rolling there's this kinda of ticking sound, that is always associated with westerns...

anyway, do you know from which movie this famous scene is taken of, or more accurate, where did this scene, if ever, first appear on the screen?

thank you very much in advance.

i think it's called a 'tumbleweed'
