Jules and Laurie try to have an amazing night, but Laurie isn't feeling it. Andy and Ellie try to stop a gang of bullies. And Travis and Grayson help their high school counterparts win a girl.
Seeing that Andy is unprepared for his upcoming job interviews, Jules agrees to coach him through it. Ellie needs a place to escape since Andy is home all the time, so she goes to Bobby's boat, only to find that Grayson beat her to it. Meanwhile, Travis and Laurie encourage Tom to date ... with disastrous results.
Grayson makes a reservation at the hottest restaurant in town, and he and Jules are determined to make it despite constant obstacles. Andy rents a special costume for Stan's birthday, but he has trouble getting it off. And Ellie starts ghost tweeting for Laurie, eventually getting lost in her new character.
