a little joke

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."
