In the old days, boys who did badly in school, had no future in respectable carreers. There only alternative was to become pirates. Since in those days pirates were all sailors, and pirates ain't to good of spellers, heck, they can't even talk no good grammer. That being, sailors don't spell good but don't need to write anyway. Since sailing is based on long tradition, sailors today still don't spell good. But, why we drink beer now, insted of rum?
