What a Memory!
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," replied the elephant, "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."
