This Yankee was walking down an old gravel road in Tennessee when he came to a cabin. There was an old man sitting on the front porch with a brown jug sitting on the floor in front of him. The old man says "Hey boy! Git over here!" The Yankee walks over, the old man points to the jug and says "You know what's in this jug?" The Yankee says "no sir, I dont." The old man says "it's moonshine. Take a drink of it!"
The Yankee tells him no, and the old man pulls out a pistol and says "You take a drink of this moonshine or I'll shoot your balls off..." that scared the Yankee, so he took a drink. It was the worst thing he'd ever tasted. It felt like it had burned his insides so badly he'd die.
The old man says "good stuff, ain't it? Then he handed the pistol to the Yankee and said "Now - point that gun at me so I can take a drink..."
