S1·E20 Soup or a Movie?

Owen and Alicia aren't happy that their best friends, Bob and Lolie, will both be coming to the wedding without a partner. So they plot to set them up, respectively, with Diana, the wedding cake caterer, and Dr Joe. Of course, they don't realize that Bob and Lolie are already sleeping with each other. At the cake tasting, things don't go exactly to Owen and Alicia's plans, but at least Bob and Lolie's secret is still safe.
