The families that work together succeed together: the Von Trapps. The Kennedys. The Mansons. The same could be said about Chicago's Elams, but they don't focus on music, politics, or murder — improv comedy is their thing. The family — the three Elam siblings Erica, Brett, and Scott, plus Brett's fiancée Jet Eveleth and Scott's fiancée Lisa Burton — have taken the Chicago comedy world by storm, honoring the mirthful memory of Del Close at the iO Theater.
