Det enklaste exemplet på nöjesläsning dyker upp i Secrets Chamber :
Trollkarlar brukar inte läsa Muggle-litteratur - bortsett från Dumbledore - men de verkar läsa om Muggles.Ron’s school spellbooks were stacked untidily in a corner, next to a pile of comics which all seemed to feature The Adventures of Martin Miggs, the Mad Muggle. Ron’s magic wand was lying on top of a fish tank full of frogspawn on the windowsill, next to his fat grey rat, Scabbers, who was snoozing in a patch of sun.

"Hope springs eternal", quotes Dumbledore in Tales of Beedle the Bard.
To which J.K. Rowling notes:
[This quotation demonstrates that Albus Dumbledore was not only exceptionally well read in wizarding terms, but also that he was familiar with the writings of Muggle poet Alexander Pope. JKR]
