I don't usually make impulsive threads like this, but I couldn't resist...I just had to share the joy of a Star Trek-related experience right after having it. I just laughed the hardest I ever have at a "Star Trek" episode, and I was surprised at when and why! I've seen this episode and moment in the past (two or three times, in fact), but it has never affected me like this before. In "Tomorrow is Yesterday", Kirk is talking to the computer and it calls him "dear". Shatner, completely straight-faced and deadpan replies, "Computer, you are not to address me in that manner" and OH MAN, I laughed so hard I embarrassed myself (the person watching TV downstairs thought I sounded like a lunatic). Sometimes the funniest moments aren't even the most overtly comedic ones...just the instances of someone playing the straight man against something ridiculous. The Mudd episodes and "The Trouble with Tribbles" are often listed as the best comedic episodes, but this one should be right up there with them. The facial expressions of the security guard beamed into the transporter room (especially when McCoy slowly disarms him) were a hoot too. Shatner's delayed line readings have been the focus of much mockery over the years, but at this moment I have nothing but affection for them. They made this line (as well as his "Please...not again" in response to Riley's agonizing singing in "The Naked Time") uniquely hilarious in a way that no one else's line readings could have been. I invite others to share favourite funny Star Trek line readings here.
