Spock; a glass cage of emotion! What, you didn't catch any of that from the show? What about the 100% cotton Star Trek Spock Expressions Black T-Shirt? Still no? Ah, I suppose you aren't versed in the subtle art of Vulcan emotions. That kind of makes sense because we humans are use to expressing our selves...the slight twist of an eyebrow, the crinkled nose, the slowly darting eye; all of those are signs that you may have a berzerk Vulcan on your hands! Say, tell you what, the Star Trek Spock Expressions Black T-Shirt should help you keep things in order. Think of it as an emotional flash card.
