There's also great lines, even from the Redshirt, in 25th anniversary on PC (of course, without the late Carmel).
Strangely, the other parents at my 8-year-old daughter's soccer game didn't find it that funny when I shouted that out at her game.
Eh, I don't think either has the right style for Mudd. The best fit (IMO) I can think of offhand would be Bruce Campbell. I think he's got the right amount of Used Car Salesman in him for the part. (I've suggested him as a reimagined Q before as well!)
For some reason, the strident computer voice that goes "Danger! Space doors are CLOSED!" in ST 3 always cracks me up. Also this: "Level, please." "Transporter room." "Thank you." "Up your shaft!"
One of the best: Worf sneezing as he carries Spot in 'Phantasms', funny, maybe because it's so out of character.
Yeah, I used to find it funny, but now whenever I rewatch it, my eye always goes back to that extra. But to be fair, Data's "UNF!" right after brings me right back. Much of that episode also belongs here, too. One of my other favs: "They just... chewed it?" "No, they infused the gum with flavor." "What flavor did you infuse it with?" "Scotch." And another from DS9: Kira snarling to Quark: "If all your little advertisements aren't purged from our systems by the time I get back from the Gamma Quadrant, I will come to Quark's, and believe me, I will have fun."
Two funniest scenes: the bar scene and fight in Trouble with the Tribbles and the bar scene and fight in Trials and Tribble-ations.
Topped in lolz by the following scene Kirk chewing the crewmen in both. "Mr. Scotty... you're confined to quarters too." "Why thank you sir, I can catch up with my techincal journals!"
TNG: "Angel One" The scene where Riker dresses in the style of the Angel One citizenry to honour Mistress Beata. Basically, it's Riker in a glittering toga that's very open in the front, revealing his chest. He's wearing at least one hanging, clip-on earring and maybe even a few bangles, but I'm not sure about those. Anyway, Deanna and Tasha are around to witness this transformation and can't stop laughing at him. It looks like they aren't acting, either, which cracks me up and gets me to laughing! The scene set-up is simple. It's stupid. But it's cute to see the women's reaction.
Lost opportunity: O'Brien following Scotty to his quarters in order to drink his private supply of "technical journals."
Tututut, we really see him reading technical journals earlier in the episode, it's porn for engineers.
Data " I am fully functional." Yar " Good." Crusher to Guinan, upon seeing Wesley with a girl in 10 forward. "Now that is the type of healthy behavior I would expect from a boy his age.....Who is she?" "Everybody remember where we parked." McCoy:"Don't tell Spock I said he was the best first officer in the fleet." Spock:"Why thank you Doctor." Kirk:"You were so obsessed with those Vulcan eyes you forgot about those Vulcan ears." "Leonard James Akhar. Has a kind of a ring to it, don't you think James?" "Definitely a name destined to go down in history, Leonard. What do you think, Spock?" "I think that the two of you are going to be insufferably pleased with yourselves for at least a month, SIR." "Shhhhhhh.........SHHH..........Well, waddaya know, I finally got the last word." CCC.
I didn't look through the whole thread so maybe someone's said this, but this exchange in "The Royale" always makes me laugh out loud Riker-What do you call this planet? Man-Earth. What do you call it? Worf-We call it Beta VIII
