Tales from the Darkside - Season 1 Episode 9 A Case of the Stubborns

In the backwoods, a family patriarch dies...only to come back, unaware that he's dead. The townspeople are up in arms, but the old man is too stubborn to admit he's dead, despite his rigor mortis, lack of appetite, and bad smell. His grandson Jody eventually goes to an old voodoo woman for a solution. Rather than magic, she provides him with a simple solution: pepper. Jody puts it in his grandpa's handkerchief. When the old man sneezes, his nose falls off, which finally convinces him to go lie down and give up life for good.
