### An Elephant And Turtle

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" commented the giraffe.

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