The rules list various subjective ways players can force a storyteller to end her turn when she:

* Gets stuck
* Contradicts the story
* Rambles
* Is too silly
* Introduces unimportant elements

What have you found are the smoothest or best ways to handle these challenges? Do you simply put it to a majority vote, a unanimous vote? Are there problems that often occur like spirited agreement to the challenges by people simply wanting to get more of an edge toward winning?

I'm looking for insights on what people have found works better and what sort of stumbling blocks they encountered with this aspect of a game that clearly requires people to be on the same page and somewhat sporting of each other to truly make it work.

Or drunk.
