Check out this awesome video mashup. I hope you relish it as much as I:
Most linguisticky moment: "smoking caterpillar"—the edit is in just the right place to get you to reanalyze hookah-smoking caterpillar in the intended way. The "remember" bit is clever too—referencing a scene from Wrath of Khan by using a similar scene from TOS without breaking up the visual feel of the video.
It's amazing how close to the surface the drug subtext was in Trek. For a similar mashup addressing a different subtext, see Closer [NSFW].
