Trivia: On May 16, 2000, 28 years after the debut of "Emergency!" on television, due to the profound impact "Emergency!" had on the American EMS system, key props and memorabilia from the show were inducted into the Smithsonian Institution's National Museum of American History, Division of Cultural History - the Public Service sector, located in Washington, D.C. Some of the items included: Original scripts, Biophone, trauma boxes, defibrillators, monitor, radios, turnout gear, helmets, and Roy's and Johnny's uniforms.
Trivia: There were no American planes shot down over the Sea of Japan during the Korean conflict. It is rumoured that producer/director Larry Gelbart knew that, but wrote Henry Blake's death scene as he was very unhappy with the way Mclean Stevenson had left the show, and was determined to make it clear that there was no way he would be coming back.
Trivia: While everyone is at the table eating supper and talking, little John Curtis taps on John's shoulder, then John turns and asks "What?" John Curtis points to his pants and excitedly says, "I got new pants," and John says, "I see that. Who got you those? Your mommy?" Then John Curtis looks offscreen, away from the other actors on set, and replies, "No, from Pat," (no characters named Pat are on the show) and without missing a beat, John responds, "From Pat? Where does she live? On the next farm?" And John Curtis answers, "Yeah," amidst all the giggles we can hear, so John answers with a smirk, "Okay, good!" This is such a hilariously precious unscripted moment, and great they decided to leave it in the episode. (00:26:15)
Trivia: "Kung Fu" was not canceled due to poor ratings, as it performed solidly during its run. It was canceled due to the physical stress and abuse on David Carradine's body, and it was wearing him out.
