Lucas and his girlfriend, Yvonne, conduct an experiment to see which of his brothers (Cyrus, Marcus, and Darius) will lie to her when she asks them about Lucas's whereabouts. Yvonne makes fake phone calls to each brother, pretending to be worried about Lucas. The brothers respond differently: Cyrus tells the truth, Marcus lies and tries to impersonate Lucas, and Darius lies and says Lucas is helping him jumpstart his car.
