A third hand joke, of sorts

Heard this yesterday, fellow that told me swears the story is true, but I tend to think it may actually be one of those stories that we normally call a Redneck Fairy Tale. Y'know, the stories that usually begin with "Ya'll ain't gonna believe this sh$t!"

Fellow over at the Gunshop yesterday was talking about some of his yankee kin being in town. They decided to go get a cup of coffee late one night. The only place open was the Waffle House. As they were driving over, he told his yankee cousin (who was of course, ignorant of the customs of the country) the old joke "What has six legs and three teeth?" The answer being "Night shift waitresses at the Waffle House."

The cousin laughed and thought no more of it. They got there, sat down, waitress came to take their order... two teeth. 'nother waitress came around to fill their coffee cups... no teeth. When they got ready to leave and went to the register the waitress who took their money had... one tooth.

The yankee cousin looks over and says "I thought you were just telling me a joke, but I can see now that you've been here before."
