Honesty Is the Worst Policy
You step to the edge of the stage, squint past the blinding lights, and blurt, "I have no idea what I'm doing up here!" The audience ROARS. They think it's a bit! Backstage, Mrs. Krendell clutches her clipboard like it's the last lifeboat on the Titanic, mouthing words you're pretty sure aren't in the script.
Encouraged, you bow. They cheer harder. You could get used to this.
