An elephant was drinking out of a river one day, when he spotted a turtle asleep on a log. So, he ambled on over and kicked it clear across the river. "What did you do that for?" asked a passing giraffe. "Because I recognized it as the same turtle that took a nip out of my trunk 53 years ago." "Wow, what a memory" said the giraffe. "Yes," said the elephant, "Turtle recall".
