Plot
While consulting her doctor about a rash, Elaine notices that her medical chart notes her as "difficult". When Elaine objects to the description, he dismisses her without examining the rash. Elaine tries to sneak her file out of the doctor's office, but he catches her and takes it back. She tries other doctors, but her chart is passed on to her newer providers and they likewise refuse her treatment.
Kramer says he can get Jerry a refund on a finicky stereo that is two years out of warranty. After Jerry lets him take the stereo, Kramer smashes it and mails it to him in an insured package, intending Jerry to claim it was destroyed in transit. Jerry refuses delivery of the package since he was not expecting it and it has no return address, but Uncle Leo accepts it in his stead.
