Oh, here's another

I hope this one can be read. This is the transcription of an actual event. I was appearing the "The Mousetrap" with a group of experienced repertory people. My character was stuck in a scene where I had nothing to do or say for what seemed like twenty minutes. At that point I had a one-word line to justify my presence on stage. I spent most of that time going over that one word to make sure I didn't screw it up, which I have been known to do, only to hear that one word delivered by someone else (who was supposed to say something along the line of "But that's crazy!"). What to do?! What to do?!
Years later one of the other performers was doing a crossword puzzle and came across a clue for a six-letter word for "nonsense" that had a "p" and an "f" in it. Up until then, she thought I'd made the word up.
Hey, I'm not that good!
