The Partridge Family s04e02
Titre original : None But the Onely
Keith wants a date with Dina, the new girl in school, but Laurie tells him she has warned Dina about his reputation and the new girl won't go out with him.
Furious, Keith comes up with a scheme. He writes a letter to Laurie's ""advice to teenagers"" column in the local paper, saying he's new in town and wants to make friends, and singing it Onely (the capital L on his typewriter doesn't work). He hopes Laurie will arrange a date between Onely and Dina.
The scheme is about to work when Laurie discovers the missing L on Keith's typewriter and realizes who Onely really is. With help from Shirley and Reuben, she convinces Keith that she thinks the letter writer is unbalanced. She then completes her revenge by arranging a date between Onely and Dina, whom she has filled in on Keith's original scheme.
When Keith meets Dina, Laurie is with her and the whole story comes out. Keith apologizes and Dina, flattered, accepts a date for the next evening.
