One day a mime(哑剧演员)is visiting the zoo and attempts to earn some money as a street performer. As soon as he starts to draw a crowd,a zookeeper drags him into his office.The zookeeper explains that the zoo's most popular attraction,a gorilla(大猩猩),has died suddenly and the keeper fears that attendance(出席人数) at the zoo will fall off.He offers the mime a job to dress up as the gorilla. The mime accepts.

The next morning the mime puts on the gorilla suit and enters the cage before the crowd comes.He soon discovers he can sleep all he wants,play and make fun of people and he draws bigger crowds than he ever did as a mime—the job he likes but loses.

However, with days going by,he begins to notice that the people are paying more attention to the lion in the cage next to his.Not wanting to lose the attention of his audience, he climbs to the top of his cage,crawls across a partition(隔墙),and dangles(悬挂)from the top to the lion’s cage.
