My favorite Star Trek episode!

What is your favorite Star Trek episode? :)
Everyone has their own, I am sure! Well, I have my own too!
Now, I know that not many people liked the Star Trek: Enterprise TV-series, but that is where my favorite episode comes from. As for the series itself, it is not my favorite part of the Star Trek saga, but i watched it a couple of times anyway. It is currently running on the national TV in my country. Still, despite all the reservations many people have, I believe that it could have been one of the best  ST series, but we'll talk about that some other time. Now, lets focus on my favorite episode.
It was episode 2 of season 2: Carbon Creek! It all starts with T'Pol having dinner with Archer and Tucker. She soon starts explaining how Vulcans actually met humans much earlier than the books say. It was in 1957 during the Sputnik launch. The Vulcan research ship crashed near a small town of Carbon Creek and three Vulcans, one of them being T'Pol's grandmother, had to live among humans for a couple of months... Isn't that great!? I hope some of you watched this episode too! Serious and logical Vulcans living in the paranoid Cold War era. They had to find regular jobs like plumbing, or working in the mines, but they also discovered a talent for playing a game of pool every now and then. This is all fun and games, but what imprinted this episode in my mind was the ending. Did you know that Vulcans invented the Velcro? Yes, Velcro is an alien gift to humans! :D Well, Archer and Tucker couldn't believe what they heard and they were reluctant to accept the story. T'Pol, like only she can do, left them in doubt by telling that it was only a "story" like they wanted in the first place. Still, later in her quarters, she takes out an old, vintage purse from 20th century Earth.
Why do I like this episode that much? Come on! The Vulcans invented the Velcro! Can it get better than that!
