The episode you mention is "The Squire of Gothos" where Trelane (played by William Campbell, who also played one of the first Klingons, Koloth), offers a greeting to the Enterprise "Salutations and felicitations, Hip-hip Hurrah... Tally-Ho!"
One could argue that Trelane's species was reminiscent of the Q, albeit child-like, as he commanded an entire planet which could outrun the Enterprise at warp factor 5 and he can control matter like a replicator.
TRIVIA: Trelane's father's voice (heard at the end of the episode) is that of James Doohan, our beloved engineer, Montgomery Scott.

Well, that would be a bit of a spoiler. But Spock is loyal (ugh, emotion) to his friend and Kirk. So, even though Spock and Sybok are half brothers Spock remains loyal to the Captain.
The planet Vulcan is Spock's home world .Mr. Spock comes from the planet Vulcan .Vulcan.Vulcan, of course
Spock is seen petting Isis , the black cat , in the episode "Assignment: Earth".
Spock was blinded for only a brief period of time in an ST-TOS (Star Trek: The Original Series) episode titled: "Operation: Annihilate!".
Evil Spock and Evil Kirk . . . . . . . . Actually it was Spock, and just Spock (not Kirk), but in the alternate universe in the episode, Mirror, Mirror, so this alternate Spock (goatee, and all) has become known as "Evil Spock"; and, actually, (Evil) Spock said: "Terror must be maintained, or The Empire is doomed. It is the logic of history."
The Corbomite Maneuver.
Mr. Spock's consciousness was hidden in Christine Chapel's mind after Henoch destroyed the vessel it was contained within in Star Trek The Original Series episode "Return to Tomorrow".
From the original series : episode 29 - "Operation: Annihilate!"
I don't know if anyone can objectively say what the best Spock episode is, especially when to a large degree it's a matter of taste. Even making an humble but honest effort to do so is likely to result in fierce debate. However, here are my favorites... The Galileo Seven & The Tholian Web - Spock's leadership at its finest. The Immunity Syndrome - Spock puts his life on the line to save the Enterprise. Other episodes worth mentioning... The Menagerie Parts 1 & 2 - Spock hijacks the enterprise in order to transport his previous commander to a quarantined planet. Two of the most famous episodes, but to an extent just an excuse to work in most of the footage from the pilot episode. The Paradise Syndrome - Spock in command (in this case of the Enterprise), but not with the success of the aforementioned episodes. Amok Time & Journey to Babel - Probably the most relevant Spock "origin" episodes, Journey to Babel being the better one in my opinion. The Enterprise Incident & The Deadly Years - Episodes in which Spock is forced to question Kirk's competency. The Naked Time - Spock is forced to reveal inner-most feelings. More believable (less over-the-top) in my opinion than the instances in "This Side Of Paradise" and "All Our Yesterdays". In my humble opinion, The Menagerie and All Our Yesterdays were Spock's best. This Side of Paradise was Leonard Nimoy's personal favorite. The Naked Time was the episode which caused Nimoy's fan mail to increase and Spock to become Star Trek's most popular character. Spock was the only character in every episode, so everyone choose your favorite!
In "The Original Series" Mr. Spock was already onboard as the Science Officer; both the Pilot episode, and the released series. In the latest movie, Kirk met Spock when he 'cheated' at the "Kobayashi Maru" test, or at the trial quickly following it.
It is a Vulcan phrase for "Go to hell." It was used in a Big Bang Theory episode Spock Resonance.
It was on the original Star Trek tv show. The computer was programmed to find the final digit of pi. As pi has no end, the computer was endlessly working on that which could not be solved. Credit to Mr. Spock, who was the Science Officer on board the Enterprise, and a Vulcan.
Spock's heart (as established in the Star Trek episode "A Private Little War") is located where a human's liver is located. This allows him to survive a bullet shot through the back where a human would die.
