I had a bit of a chuckle the other night when I watched 4 episodes of Murder, She Wrote with 4 guests from 4 different Star Trek series.
Kate Mulgrew, Rene Auberjonois, Levar Burton and George Takei. I believe all of the episodes are in season 3.
The episode with Levar Burton also had Ernest Borgnine(sounds like a Trekish name, eh?) and Adam West!
