[Karl/PA]

A Navy destroyer stops four Mexicans in a row boat rowing towards California.
The Captain gets on the bullhorn 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 !"
The entire crew of the destroyer double over in laughter. When the Captain is finally able to catch his breath, he gets back on the bullhorn and asks, "Just the four of you?"
The same Mexican stands up again and shouts, "No, we're the last four. The rest are already there!"
