(Based on a character I played in a theatre skit): If your party is having difficulty staying on the quest, simply introduce the Mystery Man: A wandering wizard guy who subtly infers that you should get on with your quest. To help, he will give you something from the following D20 chart: 1-10: a hot dog (or your universe’s equivalent). 11-19: a big lore dump. 20: an extremely OP item.
