The Great Grape Ape Show

To Sleep or Not to Sleep (1x27)

Air date: Nov 29, 1975

Grape Ape starts sleepwalking, and unconsciously starts performing great acrobatic feats all around the city. He is soon hired to perform the greatest stunt of all: cross the Grand Canyon on a thin wire. The only problem is, that while he's awake, he's scared of heights.
