Sheldon finds Charlotte at Oceanside and tells her he can't do the sex-ed seminar at the senior center with her, so he pitches Cooper to replace him. She watches Cooper walk by in a cape, with one of his little patients. She's like, "No!" Because he's only great with five year olds. Sheldon tells her she has to put herself out there if she wants to win Cooper back, which she tries to deny, but when he tells her his advice is brilliant, she doesn't really disagree. Meanwhile, at Pacific Wellcare, Fife and Pete are touching base on some study that doesn't matter other than it tells us Naomi's out of town, forcing these two to talk. Pete thinks William told Naomi about his ALS, and doesn't know when they're coming back. Fife wants Pete to focus on the ALS study stuff so they have a reason to. Back at Oceanside, Charlotte asks Cooper to help her at the senior sex ed. She tells him of the dangers of old people having sex, since they're all on male-enhancement drugs, and since they don't use protection since they don't have to worry about pregnancy. He tries to say no, but she says she needs a man, which seems to almost convince him. She's actually being nice, too, which also might help her case

Hospital. Dr. Ginsberg fills Addison and Eddie in on why she can't help Kayla. Eddie's surprised and tries to get her to change her mind, but she says there's nothing she can do. Just as she turns to walk away, Little Shepherd asks her, "What about cannulating the aqueduct of sylvius?" I love when they speak gibberish on this show, but she explains it means passing a stent to drain the fluid build-up. Ginsberg's annoyed at Little Shepherd for questioning her and getting Eddie's hopes up, because she says it's an experimental thing that won't work. Little Shepherd screams out her qualifications and says she can do it, so Ginsberg fires her. Addison just watches on, so above this. And I'm not even being sarcastic. She really is above this, and even I can admit that.

Senior center. Cooper and Charlotte are filling all the oldsters in on the risk of STDs in a place where they have so much leisure time and are basically old sluts. Charlotte urges them to flash back to high school and start using condoms. She pulls out a goldfish bowl of them, and all the oldsters just watch without reaction. Cooper's stifling giggles as Charlotte starts to fill them in on all the ways to get pleasure safely, without penetration. One old lady gets up and leaves.
