SBTB- Model Students (S2 E6)

Zack convinces Belding to fire the nerds who own the student store so that the gang can reopen it. Unfortunately, no one wants to come in, so Zack and Screech secretly take pictures of the girls' swim team to sell in "The Girls of Bayside" calendars. The girls are then invited to pose for a professional photo shoot, but only Kelly is invited to Paris, which leaves Zack out in the cold.
