Spock was one of my two role models as a kid (the other one being Phileas Fogg). I also admired Seven of Nine a lot, and took my user name from the Borg kid Icheb (who was a classic grind). I particularly liked "Deep Space Nine" since a lot of the main characters were outsiders - Odo, Quark, Nog, Garak, Worf... The episode with Nog and the hologram Vic Fontaine is one of my favourite.
The Data episode "Elementary, Dear Data" awakened my interest in Sherlock Holmes, as well as in actor Daniel Davis (who was a hoot as Niles in "The Nanny").
