The Stage Trick is an episode.
Little Bill's class is performing a song in the spring pageant, and he is excited about his role as the Grass. During rehearsal, he gets stage fright and forgets his lines. Miss Murray tells him that it's okay to get nervous and stage fright is normal, but Little Bill is afraid of freezing up in front of the audience and says he wants to quit. Hoping to make everyone feel better, Miss Murray gives the kids a Stage Trick to combat the jitters: just before you go on, you take a deep breath and blow the fear away. Little Bill does his trick right before his big speech, and after the performance, April comments on how she enjoyed the part where the wind blew before Little Bill's song.
