Television's Halloween shenanigans continue on "Open House of Horrors," tonight's episode of Modern Family, when Claire (Julie Bowen) is forced to tone down her normally over-the-top decorations and keep it kid-friendly. Her realtor hubby Phil (Ty Burrell) decides to help her by holding an open house on Halloween (hence the episode's name). Mitch (Jesse Tyler Ferguson) and Cam (Eric Stonestreet) host a very festive costume party, as Gloria's (Sofia Vergara) pregnancy hormones shoot into overdrive, upping the drama factor between her (note the amazing alien getup!) and husband Jay (Ed O'Neill). Tune into ABC tonight at 9 p.m. EST to see what other hilarity ensues when the entire crew gets in costume.
