T3, E5: In the middle of the night, a Hell's Angel-type biker named Snake zooms up on his motorcycle and rings the Partridges' doorbell. Irritated at being awakened, Shirley and the rest of the family feel obligated to listen to this friend of Laurie's tale of woe. He wants to commit suicide because after breaking all convention by proposing to his girlfriend Penny, she has the audacity to hang up on him. When Shirley realizes that Snake's proposal took place over the phone, she patiently explains to him that a marriage proposal, being the most important event in a girl's life, should not take place over a telephone. She suggests that he dress in a tie and jacket and go to propose in person. But Penny again refuses, for she feels that Snake is making fun of her by having donned such fancy clothes. Laurie goes to visit Penny and tells her that Snake will kill himself if she does not accept his proposal. Finally convinced that Snake truly loves her, Penny rushes to the Partridge house, where he has temporarily taken residence, and falls into her lover's arms. Shirley generously offers to hold the ceremony at her house, where everything goes without a hitch...and afterwards the newlyweds mount their bikes and zoom off.
