All the modern SEO-heavy links lend themselves to modification. You can give someone the URL https://www.amazon.com/fnord/dp/0440539811 and he may say "oh, I've read that, fine book" and won't have noticed anything peculiar about the URL.

(Using the male pronoun seems appropriate for that book.)

Lighten up with this: https://www.amazon.com/Illuminatus-Trilogy-Pyramid-Golden-Le...

There will be plenty of more serious stuff to read later.
