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.
YMMV: David Attenborough
Crowning Music of Awesome: His Life of Birds series of documentaries (the theme music and the birdsong).
The Life of Mammals theme isn't half bad either.
Heartwarming Moments: The BBC fare-welled him by creating a sheet full of fictitious programs crediting him and distributing it.
The infamous scene of the baby seal walking along a beach; only to be eaten by a breaching killer whale. The scene was entirely unintentional and possibly one of the greatest shots from any documentary ever produced.
The Lyre Bird. There's a reason it has over 9 million hits as of 2012, and counting.
