227 - Season 3 Episode 22
My Aching Back

When a movie is being shot outside 227, Sandra asks the director if there is any role not yet filled. He gives her a line to say (""Officer, he went that way""), but she cannot say it as naturally as Mary, so he recasts Mary in the role. Sandra is upset. Mary is so nervous, she practices the line day and night until finally she becomes so stressed that her back goes out. Rose brings a chiropractor to her house to relive her stress and straighten her up (she was bent over before). When it comes time to say her line she does it well. Sandra winds up with a role after all-- the dead homeless person on the apt. steps.
