While taking a long drink at a pond, an elephant happened to glance up and spot a giant snapping turtle lazing on a nearby stone. It's eyes narrowing, the elephant lumbered over and wacked the turtle repeatedly with his trunk. And, for good measure, he raised a foot and squashed the turtle flat with a mighty stomp. A zebra, passing by, saw this attack, and approached the elephant with intention to investigate. He arrived just as the elephant was shaking his paw disdainfully to dislodge the remnants of the turtle. "Why did you do such a such a vile deed?", neighed the zebra.
"This is the same animal that bit the tip of my trunk over 8 years ago!"
"How can you be so certain?", inquired the zebra, "you would need to have an infallible memory!"
Raising it's head proudly, the elephant said, "Turtle recall!"
