S2, E4: Shirley is accepted to a class in psychology in college, and she learns that Paul Bruner, a freshman in her class, has a crush on her. On the first day of school, Paul comes by the Partridge Family house to ask Shirley for a ride to a lecture given the following night in connection with their class. Paul anticipates an amorous episode to take place en route and quite unexpectedly, the car does run out of gas on the way home. The family teases Shirley mercilessly for using such an old trick and Paul's parents pay a serious visit to look into the supposed romance between their son and Shirley. Their visit alerts Shirley to the fact of Paul's attachment to her. With the help of Mr. and Mrs. Bruner, Shirley decides to end the romance with a special dinner for Paul. That night, Paul rings the doorbell to find Keith Partridge greeting him...much to his astonishment. He is introduced to all the other members of the family and finally realizes that he is in the midst of the famous Partridge Family - and - Shirley is the mother of the group. The situation is greatly improved, however, when Laurie enters the room. Paul's face lights up as he meets another female Partridge - one much closer to his age. After dinner, Paul bribes Danny with 25 cents to leave the room so he can be alone.
