T*R*E*K: "Mr. Spock, you have command", "Vulcans never bluff", and "Welcome aboard, sir"

Summary: Decades before I started asking myself questions like, What if King Arthur were a starship captain, or a MASH surgeon?, I asked, What if James T. Kirk never existed but Hawkeye Pierce was born 300 years late? The title of a T*R*E*K piece is a line from the original scene which doesn't appear in the T*R*E*K version. (Here's an overview of the T*R*E*K chronology.)

Setting/spoilers: These are three scenes from Doomsday Machine. Crossposted to scarfman mash_fic trek_fanfiction trekfics
