In Kruger National Park, South Africa, an elephant grabs a stick with his trunk and puts it on his head in front of a rhinoceros. If this behavior suggests a desire to impress the rhinoceros, it is actually a simple invitation to play on the part of the elephant. Unfortunately, the rhinoceros is not in the mood for fun and charges the elephant, which responds by picking up the stick and throwing it at the rhinoceros to defend itself.
