An elephant was drinking out of a river one day, when he spotted a turtle asleep on a log. Without apparent reason, he ambled on over and kicked the turtle clear across the river.

"What in the world 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," the elephant explained.

"Wow, what a memory," said the giraffe.

"Yes," said the elephant, "I have turtle recall."
