MODERN FAMILY - "Treehouse" - Hanging out with Shorty (Chazz Palminteri) and his girlfriend, Darlene (Jennifer Tilly), makes Gloria envious of how much those two do as a couple, so she gives Jay an ultimatum to step it up for a night of salsa dancing or else. Meanwhile, Cameron take a bet a little too far when Mitchell and Crispin challenge him to get a hot girl's (Leslie Mann) number at the bar, and Phil builds a tree house for Luke, but ends up being the one to make a new friend (Kevin Hart), on "Modern Family," WEDNESDAY, NOVEMBER 2 (9:00-9:31 p.m., ET), on the ABC Television Network.
