Ruff's at his wit's end. He's a loss for what to get for Charlene's birthday, and he's suddenly hearing a mysterious voice no one else can hear. At first he thinks it's because of his sensitive hearing, but then he fears he's lost his mind. Out of desperation, he sends Isaac and Liza to meet with an audiologist to find out everything they can about hearing. And just in case the voice is right about the cookies, he sends Sterling and Brian to a cookie company. Bethany and Talia stayed in Studio G for the Half-Time Quiz Show. Can Ruff find out where the voice is coming, and why he can still hear it?
