Logo: she (possibly portrayed by another cat) is hooked on life support on a hospital bed throughout the last credit roll. The credits run as usual over a picture of the MTM circle, with life support equipment attached on either side. You can hear the beeps of the heart monitor over the end theme, too. After the credits complete, the company name fades in and Mimsie flatlines and dies, with a long, high-pitched beep heard. This variation is especially rare, as reruns of the series finale plastered it over with the typical credits (As a sidenote, the actual cat, Mimsie, died in 1988, the same year St. Elsewhere ended).
Scare Factor: Medium to high, due to the extremely upsetting and disturbing subject matter. If the description is acurrate, the Texas Wheelers variant falls under this as well.
