Ciccio is in bed pretending to be sick when his grandparents show up. They have a gift for him. At the clinic, a woman shows up and is examined by Mariano, but there's a problem.

Giulio takes Lele to an exhibit in order to have him meet the lady from the fax. Lele goes home only to find a new guest, not a human one.

Mariano is seriously worried about the incident in the examining room. Some people can't help but tease him, however. At home, Ciccio is still "sick," but isn't thrilled with being served soup rather than lasagna. Giulio is being an idiot as usual, teasing Lele about Irene in front of the children.

The whole family is reacting to the new situation with Irene, a possible date for Lele. Giulio is there too, putting a lot of pressure on Lele who is quite reluctant.

Giulio shows up early to the house to find out how things went between Lele and Irene. Lele gets teased by just about everyone about his "wild night." At the clinic, the woman who had accused Mariano of molesting her shows up again. This time it is Lele who has to deal with her.

Lele gets a surprise visit at work. Later, he discusses it with Alice. Mariano comes back to work with some baccalà, a sort of salted codfish that lots of people love, but lots of people hate.

Ciccio and Libero are watching TV when Alberto comes to ask about his tee shirt, and the doorbell rings. It's someone about the dog. Lele goes to Irene's place to talk to her.
