Dogs are an iconic part of old-timey things. Some of them even existed before Mr. Presley took his title as the King of Rock and Roll. In fact, I have it on good authority that the lyrics in his song were a reference to the idea that a person could be as useless as a hound dog.
Which came first? Elvis recorded You Ain't Nothin' But a Hound Dog in 1956. Interestingly enough, however, he was not the first to sing it. In fact, the first release of the song was three years earlier, just barely eking out the creation of the highly-popular hound breed of canines by a full 18 months.
And furthermore, since I created this thread and titled it with the word Attractions and not Rides, it is completely appropriate. Some people are attracted to the classy stuff.
