Twilight Sparkle: And after this astonishing reveal, we show up?
DM: <sigh> Yes.
Pinkie Pie: Jump!
DM: You... land safely. Thank goodness the cloudwalking ritual didn't require any double-checking.
Rainbow Dash: Eh, I would've caught ya. Again.
Pinkie Pie: No, that was Twilight!
Rainbow Dash: Oh yeah.
Twilight Sparkle: As fun as it is to recount the multiple times I've plummeted to my death, can we know the result of my Arcana check now?
DM: Shortly after memorizing the scroll, Twilight Sparkle works out that a secondary magical effect had been woven into the wings enchantment. Specifically, a glamour designed to make them appear especially and enthrallingly beautiful to anyone who gazes upon them.
Twilight Sparkle: You don't mean...
DM: Unrelated, what are everybody's Will defenses?
As a DM, I've uttered the words "Just going to roll these for no reason..." a few times. One party member usually responded with "Just going to not believe you." pretty much every time.
The lesson is to actually roll for no reason sometimes.
Heh heh, nice response by the player. My kind of snark. :D
On occasion I've rolled for no reason. Once in a while if I'm feeling particularly evil, I'll ask a PC to roll a check that sounds relevant and then hand them a note that reads "you notice nothing odd" or even "I'm just instilling Paranoia, don't mind me. Have 10 exp to buy your silence". XD
As a player, I've always been a dice-fiddler: When I'm not "on turn," I'm sorting by size, making patterns, setting up clusters for different uses, making Insight checks to see which d20s are going to behave well, etc. I'm still attentive, I just have twitchy hands.
I've carries this over to my DM roll as well. So when we're playing, I'm rolling my d30 around in my hand, or making idle rolls any time I'm not actually talking. I use my "notes" as a rolling surface, so it's relatively muffled, but the sound of rolling dice is something I have habituated my players to.
Mind you, we play online. I can just *look up* the relevant numbers on character sheets.
It's when I use the online roller, or ask "So what's your AC again?" that people start freaking out.
During a segment at the bar where the players worked between adventures I laid out the bar in sections and put down a bunch of d6 to represent people. I put them all down with the 1 pointed up. Then, while they were talking, I would occasionally move the facing on one or two dice back and forth between one and two.
After doing this a few times one of the players noticed and asked what I was doing. 'Nothing.' I followed that statement by changing three dice from one to two and one die from two to three. He repeated the question. 'Nothing, continue.' He declared he was making a perception check in regard to the person represented by the die that was currently at three, and I allowed it on the premise that his job is security and hunches exist without actually meaning anything. And also because his perception was pretty bad.
He rolls poorly, and I once again change several dice. The three is now a four, two of the twos go back to ones, and a one goes to a six. He is freaking out, and some of the other players start calling for perception checks too. I deny them because they are preoccupied with their own conversations.
Some stuff does end up happening eventually, but the dice never had anything to do with anything. I just get fidgety sometimes and mess with things. The latter half was just me messing with the guy's head, and loving every moment of it. And he can't even dismiss it either, because that event helped me identify him as the paranoid one, and so I sometimes will do things like that and have them mean something, just often enough to keep him wondering.
Lots of rolls have been made when no roll was required, and some of those rolls would end up becoming parts of the game's canon. As one example, I'll roll a d20 with tags like "(I roll to see if Other Character will finally get laid or not)" or other silly and dumb things. I'm sure that were I to ever DM, I'd do so.
Nah, I prefer to be quite explicit with a 'related to that' or some such - more amusing to be bluntly obvious, though both styles of sarcasm have their merits.
Me: "Speaking of chocolate pudding, does anyone here have a pencil I can borrow?"
Them: "What the heck does that have to do with chocolate pudding?!"
Me: "It doesn't. But we *were* speaking of pudding, yes?"
I like to use that phrase with a subject that was never part of the prior conversation. THe nonsequitor tends to grab the party's attention back to me when I want to move things along.
Party: *discussing how to disable an alarm* Me: "Speaking of my father's old Pinto, gimme perception checks."
I sometimes roll a d100 when I want to create tension. I've had the monster ready to go since a month ago, but the players think they are now facing a random encounter that could be anything from the bestiary.
Similarly, if a player starts to talk OoC about how they're invincible, I'll ask them about their save with the lowest bonus.
I'm going to guess that the only one to fail their roll against enthrallment is going to be Rarity herself. It would certainly explain the "admiring her own reflection" scene.
Many many maaaany moons ago we had one-weekend campaign going on and the party went down into a hall.
Death was everywhere, bodies decaying and such... Then the GM said "Saaaayyy... Everybody roll a D20"
One of the guys was a tad older and more experienced with DnD and he caught on, immediately covering his mouth in-game. We followed his actions shortly after. Of course we still rolled D20's, and then we moved on.
On the post-game recap I did ask the GM what my 7 had entailed for me and he went "Oh yeah, you caught a horrible disease, it would've set in in a matter of in-game days. Depending on your throw you had a *chance* to survive."
In a one-shot I played, I got boiling soup poured on my leg and then had it amputated. In a setting with medieval-level technology.
Ironically, I was the only member of the party to survive that day, but I did die later of tuberculosis. After giving it to the doctor who treated me, and then to the local cult leader.
There was a time when I had a rogue who specialized a lot in stealth and going unnoticed. One time while he was sneaking through a noble manor I had him roll his hide, move silently, and then asked him to roll spot and listen.
"Why?"
"Just to be sure."
". . . 18 and 17. Why?"
"You don't think you notice anything of importance."
"Oh come on."
"You may proceed."
". . . I don't wanna, now."
"If you keep standing here in the hall, there's a higher chance of getting noticed."
