The original science fiction TV show, Star Trek, was only on the air for three years, but it was just the beginning. Over the past 50 years, there have been many Star Trek TV shows and movies loved by Star Trek super fans, called Trekkies. Dr. d’Armond Speers says that he is not a Trekkie, but some people don’t buy it. For the first three years of his child’s life, he only spoke to his son using Klingon, an alien language invented for the TV show.
