DM: The mares notice you and are all like:
Stepford Mare 1: Ohhhhhh! Aren't you the most adorable thing! Come join us.
Smolder (RT): No. And I leave.
DM: Back into the tunnels, then. The mares don't say anything or try to stop you. There are many curved, interlocking passages that almost seem to loop in on each other.
Smolder (RT): I just try to keep heading in the same relative direction.
DM: After about a minute of going what you were pretty sure was north…
Stepford Mare 1: Welcome back!
Stepford Mare 2: Come sit by me and let's compliment each other!
Smolder (RT): Are there multiple exits?
DM: Yes.
Smolder (RT): And the tunnels… They form the shape of overlapping flower petals, don't they.
DM: Ummm… <scribble> Yyeesss.
This has been covered before, but it bears repeating: If a player comes up with something cooler than your original idea, always take it and pretend that was the plan all along if at all possible.
PC using subtlety to kill a powerful being that trusted them.
They are invited to discuss some works they could do for him. And the discussion end very fast, with a short curb stomp battle because the being didn't expect to be attacked by his 'faithful' minions.
Happy, the PC opened the door and walked in the same piece they left. Again, again ... and again. Before realizing that no, thousand years old near divine being would not be that gullible.
After a while the real being arrived, more amused than angry, and asked them if they would try to kill him now or suffer punishement.
Strangely PC did the wise thing and took punishement rather than fight the being able to distort space/time without any dice roll.
Fun fact: this encounter was the part of the show where I realized that Smolder was supposed to be a girl. I don't think anyone had referred to her in the third person until now.
If anyone's still around, the story time I'm more curious about is:
Tell a story about a better idea a player had than your original idea so you stole it. And if it was as obvious to the players that you did like this GM here.
I do this fairly often, because I'm playing with kids at work and need to keep them engaged. If they want to fight gargoyles, we fight gargoyles. If they want to raise a salamander as a pet, have a pet salamander. What they don't know is that they're playing right into my hands, since I can have the salamander burn down their base or the gargoyles fly off with the treasure. Whatever happens, I have ready made plot hooks to keep them going for days. So long as they come back to the table, which is another story...
