Once there was an Antartian that was down on his luck. In order to get some money he decided to kidnap a kid and hold him for ransom. 
He went to the playground, grabbed a kid, took him behind a tree and told him "I've kidnapped you." 
The Antartian wrote a note saying "I've kidnapped your kid. Tomorrow morning put $10,000 in a paper bag and put it beneath the pecan tree next to the slide on the north side of the city playground. Signed, An Antartian." 
The Antartian then pinned the note to the kid's shirt and sent him home to show it to his parents. 
The next morning the Antartian checked, and sure enough a paper bag was sitting beneath that pecan tree. The Antartian opened up the bag and found the $10,000 with a note. The note said, "How could one Antartian do this to another Antartian?!"
