A U.S. Navy destroyer stops four Mexicans rowing towards Texas .
The Captain gets on the loud-hailer and shouts, "Ahoy, small craft. Where are you headed?"
One of the Mexicans puts down his oar, stands up, and shouts, "We are invading the United States of America to reclaim the territory taken by the USA during the 1800's." The entire crew on the destroyer doubles over in laughter. When the Captain finally catches his breath, he gets back on the loud-hailer and asks, "Just the four of you?" The same Mexican stands up again and shouts, "No, we're the last four. The other 20 million are already there!"
