Swiss Army Man

Hank Thompson, a man marooned on an island, is on the verge of hanging himself, but sees a corpse wash up on the beach. He tries to resuscitate it, but the corpse bemuses him with its incessant flatulence. As the tide begins to wash the corpse away, Hank watches as its farts propel it around on the water. Hank immediately mounts the corpse and rides it across the ocean like a jet ski, landing on a mainland shore but far from civilization. That night, the two of them hide in a cave from a rainstorm, and after the runoff pours into the corpse's mouth, Hank realizes the next morning that the corpse has yet another power: it can be used like a well for a seemingly infinite source of drinkable water. The corpse also begins a slow transition into speaking and acquires a grasp of the English language, adopting the name Manny. Hank and Manny continue their quest, using Manny's erections (fueled by a swimsuit magazine they find) as a compass. Manny has forgotten everything about his former life, and Hank tries to teach him various concepts about life, but Manny's childlike and shameless interpretations of these concepts conflict with what Hank considers socially acceptable behavior.
