I used to be a true Star Trek fan! I guess I still am. At the time, the special effects were really special effects! By today's standards for special effects, they were nothing. I found this segment, posted on YouTube, from my absolute favorite Star Trek show. The video is a little long--about 9 minutes. I hope you enjoy The Trouble with Tribbles as much as I do and did! You can find more of this show on YouTube. Do you see any beads here?
