Kev sings Frank a little song that goes, "I've got some money coming" and then Fiona comes in, with Lip and Debs, to remind us what's going on. What's going on is that Carl's finally got his arm taken care of, and they inform him that Liam actually is his son -- "I thought that was always a rumor about Nana Gallagher having an affair with that sax player," as yet another example of the tone-deaf hideous dialogue in this episode -- which works against him, because now what? He wants to be on Bob's side right now.
Fiona, of course, is still ahead of the game and tries to make him promise not to sign the baby over, but Frank is all about how it's okay if Monica steals him for a little while. Frank goes on some kind of kick about lesbians and Lip finally just punches him in the fucking face, and Fiona once again makes some vague threats about ditching the family, but not even Frank is buying that one anymore, and it's just like watching a truck spin its wheels for an hour because none of this matters and even as it's happening you know none of it matters.
Patty: "Last year when I was singing madrigal, I started dating a boy in the choir. He said we were dating, but we never met outside of our make-out sessions in the rehearsal hall. I repeatedly let him touch me on my breasts, through my shirt and bra. And once, I felt his rod touch my leg. This is so embarrassing. I can't believe I let him do this. I'm so sorry."
All the Promisekeeper Dads: (Get giant boners and start drooling, because this is a bad idea in every way.)
Elaine: "I only touched one penis. Once. If I didn't, I was going to get hit with a pipe."
Elaine's fucking father: "God, why did you let my daughter become a slave to the flesh?"
Elaine, to reiterate: "I was going to get hit with a pipe."
Promisekeeper Dads: (Look for more women to blame for their own gross problems inside their ugly selves.)
