Who can you tell DM'd a snap story?

It depends. If you have something interesting or relevant to say, then it could be okay. But if it seems like you're just being random or creepy, then it's probably not a good idea.

Involve those players more in the story - building process. Maybe they are being disruptive because they feel left out. Ask for their ideas about certain plot points or characters. For example, say 'You guys seem really eager to contribute. How about you help me design the next villain?'. This way, they feel included and are more likely to let the DM tell the story as well.

Use positive reinforcement. When players do let the DM tell the story without interruption for a while, praise them. Say 'Great job everyone for letting me tell this part of the story. This is really helping the game flow'. This encourages them to keep up the good behavior.
