Who's Afraid of the Big Bad Jinx?

Lately, bad things have been happening to people whenever Uncle Joe is around. Betty Jo loses her voice. Mr. Harrington gets fired. Sam's printing press breaks down. The Cannonball rides off the tracks. Fred Ziffel's new well dries up. Joe is now getting the reputation of being a jinx. Joe is initially upset by all the talk of him being a jinx. But then he decides to offer his services as a jinx for a fee. Sam hires Joe to jinx Crabwell Corners so they don't get the new box factory. Then hopefully it will instead come to Hooterville. As hard as Joe tries, the factory still winds up going to Crabwell Corners. Kate says that proves that Joe is not a jinx. But, could there be another jinx at the Shady Rest and could it be Dog?
