Little Indian vs. Big Indian Systems

Two Indians were sitting on an unimportant Indian's log. One Indian was big and the other was little. The little Indian was the son of the big Indian, but the big Indian was not the father of the little Indian. How do you explain that?

If you answered "The big Indian is his mother", then you were wrong. What really happened was the big Indian compiled a C program that had main defined with a return value of void and, by the LAWS OF UNDEFINED BEHAVIOUR, a little Indian popped out of the floppy disk drive.
