Star Trek

Jim: Bones...I, want, you, to find, out...what's, killing, the, redshirts...!

McCoy: Dammit Jim, 3 more died during your speech.

Chekov: You know this show used to be called "Tsar Trek"

Spock: The tribbles are reproducing at will..almost like yourself, Captain Krik

Sulu: Course laid in. Arrival in 3 days

Jim: Just, enough, time, to, deliver , my, next, line.

Spock: Why do you let all these redshirts die, doctor?

McCoy: Dammit Spock, I'm an actor, not a doctor!

Khan: How do you keep beating me, Kirk???

Kirk: Your DNA is no match for my EGO!

some of these are very good - i like the Kirk slow-speaking ones - and and the Chekov line is brilliant!

yeah that one was hilarious because I can actually picture Walter K or Yelchin saying it.

I have a better one.

Q: How many Red Shirts does it take to change a lightbulb during a Red Alert?

A: Five. One to change the lightbulb and the rest to get shot covering him.

(I made that up. It used to be four Red Shirts but I changed it to five because somehow five is funnier.)

Not bad.

Here's an oldie Star Trek joke, it's been around forever.  Don't blame me if it's corny, it's really a kid's joke.  (in fact, I think I heard it as a kid):

Question: What do the U.S.S. Enterprise and toilet paper have in common?

Answer:  They both circle URanus looking for "Klingons"

Here's another one I heard on "The Nanny":

This is a Jeopardy type question (answer given first):

Answer:  The oldest star circling the galaxy.

Question: Who is William Shatner?

Hahahahaha the one about the tribbles reproducing is the best
