S4·E4 Prison Blues

After Stan is arrested for tax evasion, Grace and Karen timidly visit him in prison. Grace is so moved to help her worried friend that she moves right into Karen's deluxe apartment-in-the-sky, where she becomes a demanding guest who's soon hooked on servants, bubble baths and an extravagant lifestyle. Meanwhile, as Stan's attorney, Will struggles with stage-fright when he babbles on during a TV news interview, so Jack convinces him to polish his communication skills by attending an acting class ruled by an imperious teacher.
