Season two of FX's American Horror Story: Asylum comes to a close tonight at 10 p.m. Set in 1964 at fictional mental institution Briarcliff, and staffed by a crew of morally ambiguous nuns, (Jessica Lange and Lily Rabe), creator-producers Ryan Murphy and Brad Falchuk have provided plenty of material for a wild, occasionally terrifying ride that we're sad to see come to an end (but that will no doubt haunt our dreams for some time to come).
The hi-jinks of your favorite mentally unstable staff may be over after tonight, but you don't have to check out of the institution just yet. The US has a rich history of deeply flawed asylums that have set the scene for countless real-life American horror stories that make Briarcliff look like a retirement home.
