Del goes to see his GP, Dr. Meadows, only to find he's left general practice and gone to work at the local hospital, and a young Indian woman is his replacement. Del's unhelpful quips fail to impress her and during the examination he lies to her repeatedly about his lifestyle, pretending he is a teetotal, celibate health conscious anti-smoker. She sends him to hospital thinking he might have a grumbling appendix but after testing Del, the doctors dismiss this and can't seem to diagnose him. In a discussion in the Nag's Head, Uncle Albert suggests it might be Green Parrot Disease.
