The Switch

In her thirties, Kassie Larson is single, has not found love yet, and decides she wants to have a baby. Despite the objections of her long-time best friend Wally Mars, she chooses to do so alone because she cannot wait any longer. She also wants a face-to-face sperm donor, disdaining using a sperm bank.

Wally suggests he be the donor, but Kassie believes he is too neurotic, pessimistic, and self-absorbed. Since they are best friends, she thinks "that would be weird." He has always had feelings for Kassie, and they dated six years ago. His friend Leonard points out he missed his chance when she relegated him to the "friend zone."
