These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

April 28-29, 1977: The final two episodes contained rather racy clues for "pipe" (the smoking variety) and "boomerang" most especially, such as "In the film Walkabout, the lead male straps one against his thigh with his loincloth" and "To use one properly, grip it firmly with three fingers at the curve near the tip." These clues only manage to sound funnier when one hears and sees Alex Trebek read them so seriously.
