Cliff Hanger and The Amazing Hippopotamus Sculpture is Episode 414 of The Adventures of Cliff Hanger.
Cliff Hanger, as always, is seen hanging from a cliff. Then he sees a sculpturist making a hippopotamus sculpture. According to the Survival Manual, if Cliff sees a hippopotamus sculpturist, he should ask her to give him a hand. So when Cliff asked the sculpturist to give him a hand, she thought Cliff meant one of her hand sculptures and tossed it to him because she has lots of hands left. Once she tossed Cliff the hand, she went down and Cliff threw the hand away.
