Claude is throwing her first Thanksgiving for all her friends. Owen's two lesbian moms (Valerie Harper and Joanna Kerns) come to visit and share the holiday. The only problem is that his moms have always assumed that Owen is gay. Hoping to keep up the ruse, Owen asks his friends to play along, including asking Carl to pose as his lover. Meanwhile, Lydia and Kipp both get invited to Will's Thanksgiving party, where Kipp is briefly the star attraction.
