No Nudes Is Good Nudes - S2.E4

Joanie goes out for coffee with her art teacher. She says it isn't a date, but Chachi insists it is. He goes to Joanie's school to check up on her teacher and sees that he's a young blond. To avoid being seen by Joanie as she and other students enter the room, he tells the teacher that he is the model and soon learns that he will be posing nude.

Meanwhile, Al wants to join the Chicago Leopard Lodge.
