He doesn't have any money but still orders a drink. When it's time to pay, he asks the bar tender if he's willing to let him bet to pay for the drink.
The bartender asked what the hunter wanted to bet. The hunter looked up above the bar and pointed at the animal pelts hanging there and said that blind folded, if he touched a hide he would be able to tell what animal it was and how it was killed.
The bartender took him up on the bet and blindfolded the old hunter and took down a hide. The hunter felt the pelt and said, "White tailed deer...killed by bow and arrow!"
The bartender is amazed and says the hunter won the bet and doesn't owe anything for his drink. The hunter wants another drink so they do the bet again. Still blindfolded, the hunter feels the next pelt and claims, "Black bear...killed with a rifle!" And he gets another drink. This goes on all night as the hunter keeps guessing correctly and gets a drink after feeling each pelt, until he is completely drunk. Finally, in a drunken stupor the old man stumbled home and crawled into bed. He woke up in the morning with a splitting headache and a black eye and asked his wife, "Honey, I know I had a few drinks last night, but I don't remember getting into a fight! What happened?" His wife replied, "No, you didn't get in a fight, I hit you in the head with the alarm clock when you crawled into bed last night, shoved your hand down my panties, and said, "Fish...killed with an axe!"
