An elephant with a turtle

An elephant is drinking out of a river when he spots a turtle asleep on a log. The elephant ambles over and kicks the unsuspecting turtle clear across the river."Why did you do that?" asks a passing giraffe."Because I recognized it as the same turtle that took a nip out of my trunk 47 years ago.""Wow, what a memory!" says the giraffe."Yes," says the elephant. "Turtle recall."
