A blind man walked into a diner and made a strange request to his waiter. He asked if he could have the unwashed fork of the last customer the waiter waited on. The perplexed waiter agreed and handed the blind man the unwashed fork. The blind man proceeded to put it in his mouth and said, "Hmmm, the meatloaf and mashed potatoes are good here. I'll have that." 

The next day, the blind man returned to the diner and did the same thing. Now, on the third day, the waiter saw the blind man coming into the diner. He still didn't believe what the blind man was capable of, and he wanted to trick him. So he quickly grabbed a fork and asked his waitress wife, Jane, to pull down her panties and rub it between her legs. 

When the blind man asked for the fork, the waiter gave him the fork with a big smile on his face. 

The blind man put it in his mouth, and said, "Hmmm, I didn't know Jane worked here."
