This tearjerker is absolutely stunning, a series classic, brilliantly written, with superb and memorable dialogue.
Blanche's dilemma is so catching because we really all could end up facing it; would you be selfish and keep your kidney, or donate it to the sister you hate so much?
Blanche's decision is beautifully played - Rue McClanahan in general shines in this episode and proves her immense acting talent - and the hugging scene between Blanche and Virginia actually made me cry.
AND it still contains so much wonderful humour that you must almost cry from laughter - example, Blanche tells the girls about her sister's need, and Rose, not understanding: Why does she want your kidney? Dorothy roars: To feed the cat, Rose!
You have to love it.
