Neal goes out to the garage and snoops in his father's mid-life-crisis-shame-about-your-penis red Corvette, which bears the licence plate "I FLOSSEM." Remember that plate, kids, because if it, like a gun, is shown in the first act, you know someone is going to use it in the final act. Neal's snooping turns up a second garage-door opener, which doesn't work on their door.
Lindsay walks into Sam's room looking for her Pink Floyd albums. Sam asks her, "Why do people have affairs?" Lindsay doesn't have any answers so Sam asks her if she thinks Dr. Schweiber would have an affair. They laugh at the prospect of their own father having an affair and then dissolve into fits of giggles when he appears at the door clad in boxer shorts, a T-shirt, and black socks. He doesn't know what they're laughing about and they wouldn't tell him even if they could stop laughing long enough to do so. Dad barks, "Finish your homework!" and leaves.
Sam arrives at Dr. Schweiber's office for his appointment. Dr. S., who is wearing gloves, starts probing around in Sam's mouth with various instruments. I don't remember my dentist wearing gloves in 1980 but then again, I kept my eyes shut tightly and prayed for short appointments back then. Of course, that's still my coping mechanism for dental appointments. Dr. Schweiber says that Sam acted differently yesterday and it hurt him. The dirtbag dentist accuses Sam making more of his hugging Carol, then he asks if Sam has told Neal. Sam denies it and Dr. Dirtbag puts one of those plastic things in Sam's mouth to keep it propped open. Sam listens in horror as Neal's dad reveals that he didn't date much before getting married, and generally tries to rationalize his affair to his teenaged son's friend. That is just so sad. A dental check-up and TMI -- it must be pure hell for Sam.
Sam runs into Bill at school and Bill informs him that Neal was not on the school bus that morning. Neal is already seated in the class when they arrive. He tells them about finding the remote. Bill helpfully recounts a Donahue show about the secret love nests of people engaged in affairs and he suggests that Neal's dad has such a place. Neal looks at the remote and says, "There's only one way to find out."
The marching band is practicing on the playing field again and Ken is watching them from underneath the bleachers. Lindsay approaches Ken to ask if he wants her to ask Amy to go to Laser Dome with him that night. Lindsay tries to determine whether he is going to be nice to Amy and he promises to be "an angel." He asks if there's much chance of Amy agreeing to go which prompts Lindsay to squeal, "Omigod, you really like her, don't you?" Ken looks pained and says, "I feel odd."
