Open House Of Horrors
S4 episode 5 Aired on September 5, 2013

Claire has overdone it in Halloweens past and the neighbors definitely don’t share her enthusiasm, so this year she’s being forced to tone it down and keep it “kid-friendly,” and Phil has an idea to hold an open house on Halloween night. Meanwhile, Mitch and Cam host a costume party while contending with Lily wondering who her real mom is, and Gloria’s pregnancy hormones are on overdrive, making her even more hotheaded than usual.
