On January 19, 1986, Punky Brewster featured a Very Special Episode about the perils of playing in abandoned refrigerators and the benefits of learning CPR. Refrigerators were high on the list of biggest menaces of the 1980s, behind only drug dealers, apples with razorblades, and Judge Doom.
The episode is available for free on NBC.com, and here is a clip that takes it lightly but gives you a taste:
The Mental Floss oral history of this episode is great reading. Among the tidbits in here, this episode was the result of a story submission contest NBC held. The kid who won suggested Punky learn CPR, and the show's staff created the fridge story.
