Picard: No. 1, What’s that noise?
No. 1: No. 2. I’m on the pot.
Of course that never happened, because everyone’s bladder and lower intestine are hooked up via wi-fi to the transporter.
In Star Trek, the incredible rate of failure of their communicators and transporter systems. It seems every other episode had to have one of them fail, so the away team couldn’t just say “Get us the hell out of here, Scotty.”
The amazing search engine. Instantly find the exact thing you are looking for in two seconds, no matter how obscure! No five minute clicking back and forth!
And, of course, the TV or radio that, when you turn it on, instantly starts to play the item you are looking for. Same technology as the above search engine?
There’s always a parking spot where the good guy needs it in a hurry. And it’s right in front of the building.
Cops always have to meet someone/watch someone/get information in a strip club.
And, there’s never any nudity in the strip clubs! I know, it’s TV, but I swear watching those shows, I wonder why anyone goes to strip clubs. Woo! Girls dancing in bikinis! Sure do love this big city life!
Dr. Crusher and the ship’s computer tinker with the replicators to ensure every crew member is very regular.
Command policy 13.4.4b: All qualified watchstanders are to “have a movement” 30 minutes before their duty shift.
My favorite was the scene in X-Men: First Class when Charles and Eric are recruiting mutants, and they find girl-with-wings in the strip club. As incentive, Charles says “You never have to take off your clothes again.” Then they show her facing them, flapping away…with her underwear on.
I think that “alternate world” is just California. Window screens aren’t that common out here.
And then there’s my favorite enhance scene of them all.
Why does almost EVERY car have to come to a halt with a screech of tyres. I’m pretty sure I’ve even heard it happen when a car is stopping on sand.
Tyres?
Edit: Sorry. I’m trying to think of some joking way to link this mispelling to the city of Tyre…
“Tyre” is clearly the superior spelling. 
In Fringe at one point they claim to be able to use some gizmo to slow a video recording (I believe on a tape) down so much that you can see light moving.
I think you’ll find I’ve spelled it perfectly correctly old chap.
Pip pip and toodle-oo.
The Gunpoint Standoff - two (occasionally more) people have each other at gunpoint. Ten second ago, they were trying to kill each other, but now, neither of them will pull the trigger.
The Lifesaving Hospital Door - anyone who is mortally ill will be OK if you can just get them across the threshold at the hospital. That’s as long as they need to ‘hang on’ or ‘stay with me’. Once they’re inside a hospital, they’ll be fine.
The most hilarious use of this was in the movie Hitman. Three guys have come to kill the hero and they all point their guns at him. He then points his guns at two of them. Then they all point their other guns at each other, stand-off style. Uh, why are the three dudes that are working together all suddenly pointing guns at each other? As it turns out, it doesn’t matter, b/c then they all put their guns down and pull out swords. From hammerspace, I guess, b/c there’s no way they had them earlier. I’m afraid I can’t tell you what happened next, as that’s when I turned it off.
Boy, does this bother me - when someone gets shot in the leg and you see them running, or recently when I was watching Prometheus (which, granted wasn’t the most realistic movie) but when she had her c-section and then was up running and fighting and doing other things - um no.
There’s no other way to portray deep thought, angst, or relief without finding a bathroom sink so you can splash water on your face and stare dripping into the mirror.
Seriously, have you ever??? No woman with makeup on would ever do that.
The driver is always turning to look at the passenger to talk. Why don’t they just talk like real people in the car do? Look straight ahead at the road and we still know who you’re talking to.
Here’s another one: Person A (who could be a suspect, the victim, a family member, or the lead detective) has a big insight or remembers something or puts 2+2 together and calls Person B, who of course doesn’t answer.
So Person A leaves a message on Person B’s voice mail. And is it a message like this: “I just figured out that it was Lady Jane in the kitchen with the cheese grater because we found her prints on the handle and Lord Twombley’s blood on the business end of the grater.” Nooooo, of course not. Because *that *would make sense.
Instead Person A leaves this message: “I have to talk to you right away–I’m on my way to the Old Mill and I have something that will crack this case wide open!” Right then the Bad Guys come up behind Person A, knock him/her out (see comment about head injuries in an earlier post), then smash the cell phone. THEN the Bad Guys (who were eavesdropping) high tail it out to the Old Mill where they mess up Person B real bad because Lassie was at obedience school that day and not available for the rescue.
And there’s no rear-view mirror.
