Ben gets very upset when Katz throws away Bully, the stuffed bull from his childhood. Ben labels everything that belongs to him, and expresses fear that perhaps Katz wants him out, too. Katz gets out his guitar and sings some old folk songs (Ben used to sing "Immy Ack Orn"), and Ben encourages him to go to the open-mic night at a local nightclub. He does, at "The Tomcat," and Laura goes to witness the humiliation. Stanley and Julie are also there. Katz sings a song he used to sing for Ben as a child: "A boy, a bike, a heart so full/A mom, a dad, and a little stuffed bull." He whispers, "What have I done?" and asks Ben, from the stage, to forgive him. Ben goes outside "to pee for a while" and talks to Laura, who thought the whole ugly incident was "the good kind of pain." This episode features the first mention of Grace the cleaning lady, as well as one of only two glimpses of her (the other is in #105); it's also the first time we see Katz with the guitar.

• Joy Behar: Shows Laura her sweater; doesn't like men because she spends a fortune on pantyhose and they still wear the same socks they wore in junior high; feels hostile toward Katz; he says he's not leering at her, he just as a palsy in his eye.
• Ray Romano: Marriage is so new; he chose his side of the bed based on how far from the door it is, in case the Boogieman comes; he's the official Noise Checker-Outer in the middle of the night; having three young kids makes him look for excuses to leave the house; can never have a normal phone conversation ("So yeah, I just need to know where ARE YOU GOING WITH THAT COOKIE!!").
