Stand-In Room Only

There's an ad in Variety from a studio that needs a stand-in for a shark in a new movie. MisterJaw applies for the job. He is not believable as a shark. However, he gets violent and gets the job. He finds that the stand-in does dangerous stunts. When MisterJaw rescues a tied-up girl from dynamite, the dynamite explodes. Next, he is supposed to scare a little old lady. Instead, she pounds him. He greets natives after swimming to an island, but they try to cook him. Determined, he holds out until the script calls for him to dive from a 500-foot tower into a bucket of water. The shark decides to retire from movie work.
