A hyena is drinking at the watering hole one day, when he sees an elephant come for a drink.
Close to the water, the elephant stops short and inspects a turtle for a few seconds. Then the elephant rears back and kicks the turtle, making it fly the better part of a mile.
The hyena asks, “What did you do that for?”
“Well,” answers the pachyderm, “About 80 years ago that turtle bit my foot. Today I finally found that SOB, and paid him back.”
How in the name of heaven could you remember what that turtle looked like after that many years?”
The elephant replied, “I have turtle recall.”
