The Importance of Being Brian

It's Saturday and everyone wants something from Brian, but no one can find him. Brian has decided that he would rather spend the day with his new love, Lisa B. Meanwhile, Nicole, hopped up on her fertility hormone treatments, needs her brother to help her and Angelo with a car problem; Deena and Dave expect Brian to play "Barney" at their daughter's birthday party; Adam, stuck planning the wedding, wants him for some guy time; and Marjorie keeps leaving messages on Brian's phone to talk about their relationship.
