Seinfeld: Kramer's Hot Tub
Biology → Homeostasis → Hypothermia
Kramer gets a new hot tub and enjoys relaxing in it. While sleeping in the hot tub, his heat pump breaks, and the temperature gradually decreases from over 100 degrees Farenheit to about 58 degrees Farenheit. He meets up with Jerry and George in the coffee shop wearing multiple layers of clothes.
