Jay (Ed O'Neill) and his buddies meet Cameron (Eric Stonestreet), whom Jay introduces as Mitchell's (Jesse Tyler Ferguson) friend. This incenses Mitchell, who tells Jay that Shorty (Chazz Palminteri) sets off his gaydar by the way he talks, dresses and acts. (To the camera, Mitchell and Cameron discuss Mitchell's coming out to his father and that Jay had a hard time accepting it). Jay refuses to believe it, but Gloria (Sofía Vergara) agrees with Mitchell when Jay informs her of his opinion. Jay begins noticing signs after he starts watching how Shorty acts and comes to think that it may be possible, but once he offers support to Shorty, he discovers that his friend is a bad gambler with smart dress habits.

Meanwhile, Gloria gives Manny's (Rico Rodriguez) surprise date, Whitney (Kristen Schaal), a shabbily dressed young twenty-something, a makeover so that she can feel better about herself. Cameron ends up meeting Manny's date, who thinks Cameron may be the guy for her after a short conversation.
