Trivia: A constant question during the run of all the Trek series is why Klingons look so much different from Star Trek: The Motion Picture on than they did in the original series. The real reason is the movies and later TV series had a better makeup budget. However, the Star Trek: Enterprise episodes "Affliction" and "Divergence" provide a canon answer. Klingons acquired genetically engineered human embryos left over from Earth's Eugenic Wars and used them to augment their soldiers. It worked but created a virus that threatened to annihilate the Klingon race. Dr. Phlox and a Klingon doctor found a cure, but it resulted in all Klingons becoming far more human in appearance. Sometime between these episodes and the first Trek movie a cure was found, returning the Klingons to their present day "ridged-head" appearance.Grumpy Scot
McCoy: In simpler language, Captain, they drafted me!
Kirk: They didn't.
McCoy: This was your idea! This was your idea, wasn't it?
Kirk: Bones, there's a thing out there...
McCoy: Why is any object we didn't understand always called 'a thing'?
Question: When it is mentioned that Ilia is Deltan, a couple of the male Enterprise crew members (Sulu in particular) look very interested when they hear that. Why? Also, why was it necessary for her to say that she has taken an oath of celibacy?
