S4E9 Chrissy's Hospitality

While attempting to hang a shower curtain, Chrissy slips and bangs her head in the bathtub. Concerned for her well-being as she begins to feel dizzy, Jack and Janet rush her to the hospital. When the doctor emerges from Chrissy's room in tears, Jack and Janet misinterpret the situation, believing that the news is dire and that Chrissy has only a little time left to live.
