Not every adventure pits the heroes against malign forces bent on world domination. In fact, sometimes the most interesting situations occur completely by accident.
The series of misunderstandings that precipitates this adventure can without a doubt be solved quickly, quietly, and without any danger to life and limb. But considering how most heroes behave in the face of an unusual situation, such an outcome seems extremely unlikely.
A Funny Thing Happened At Carousel #5 is a real adventure, with real threats and real rewards. However, it’s anything but serious, and you as GM should plan to run it with tongue firmly in cheek. Those who do not like to mix a wisp of comedy with their adventures may want to look away before it’s too late.
