Yes. Yes they did. It's amazing that they condensed the whole plotline into one episode. I mean that could have been two whole seasons on Knots Landing. Basically Christine who is about a size 8 anyway goes to the gym looking like great shape Barbie and on the way out she grimaces at herself in a mirror, despite looking amazing. Next thing you know she's stuffing chocolates and crisps and lardy things down her gob and then puking I all up. All resolved in the last few minutes though with the help of Peter (Jesus of St Gregory) McDermott.
