Prison Blues

S4, E4: After Stan is arrested for tax evasion, Grace (Debra Messing) and Karen (Megan Mullally) timidly visit him in prison, but 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 (Eric McCormack) struggles with stage fright when he babbles on during a TV news interview, so Jack (Sean Hayes) convinces him to polish his communication skills by attending an acting class ruled by an imperious teacher (Oscar nominee Eileen Brennan, "Private Benjamin"). Shelley Morrison also stars.
