One little-known fact about The Marauders was that although they were considered a pillar of Gryffindor House and by extension Hogwarts' storied history, all members were partial to certain aspects of Muggle popular culture in their own ways.
The most famous example of one of the members of The Marauders becoming enamored with Muggle culture came upon when young seven-year-old Sirius Black snuck out of his house on Christmas Eve to attend the UK premiere of Disney's The Jungle Book in order to play a muggle-baiting prank on British Disneyphiles, but ended up enjoying the film so much he completely forgot about the prank.
For the rest of his life, the young Black cited this film as the first indication as a young boy raised in high Pure-Blood culture that maybe Muggles weren't all that bad if they were able to create something so wonderful without magic, and while he may have bad-mouthed non-magic folk while around family he couldn't help but wish he was listening to the musical stylings of Phil Harris instead.
In the later years, he discovered that his best friend James held the same sort of polite fascination about Muggles, with the two often spending nights out hitting pubs in London soaking in the forbidden culture, and always came back full of questions for friends with Muggle relations about what they had just seen.
These little snippets of information usually came from the member with the closest link to the Muggle world, namely Remus Lupin. Although he preferred to go home over breaks and alternating weekends, his friends were never that far away from his mind and as such brought back all of the non-magical artefacts he could carry in his suitcase to show off to his friends, full of amazement in how foreign these everyday objects seemed to his friends.
It was these artefacts that kept Remus grounded whenever he felt life got the worst of him; his "furry little problem" as James liked to call it, had a nasty habit of taking over his life whenever he felt stable or safe. There were times now and again when he WAS able to forget for a bit and worry about acne that came back over and over again like a horror movie villain, term papers that seemed to multiply like horklumps in heat, and act on crushes that were going to end poorly like the rest of his peers. But then, just when things were starting to go well again, that stupid donut in the sky had to wax once again and everything went to hell.
One instance in particular was when Lily Evans, a girl he was friendly with, had asked him while flipping the fiery-red hair as she did if he wanted to come along with her family and a couple of her friends to the beach over Easter Break. Remus wanted to immediately say "Of course, Lily, I'd be delighted!" but in typical thirteen-year-old-boy fashion whenever a pretty girl so much as asked him for a porcupine quill in Potions class his throat had closed up as he struggled to put a coherent response together. In the time he had found his voice, Remus embraced his inner Ravenclaw and realized that if he went swimming with Lily and her friends he would have to wear a bathing suit, and as such the bite marks on his legs would show, so he had no choice but to politely decline and rush off to Ancient Runes feeling bad for blowing her off again.
As Remus liked to joke to those in the know, at least his lycanthropy gave him an advantage in Astronomy class, he simply had to check his palms and see if they were hairier than usual to chart the moon's phases. He had been told by all his friends that the joke wasn't all THAT great the three times he had told it. But he was the werewolf and he liked that joke so screw them, what did they know?
So after a hard day's night of lowering The Shrieking Shack's property values he would slink back to the hospital wing, lick his wounds (before remembering that normal humans don't really do that) he would prop up a good book, set up his record player (Madame Pomfrey permitting), and engross himself back in the world he had left to become a wizard like his father before him.
While neither of his parents really considered them to be "real literature" by Muggle or Wizard standards, Remus was also very partial to comic books, and as such they begrudgingly made sure he was well-stocked with that and plenty of chocolate the day after Mother Nature had had her way with his body for the night. On a side note, there has to be a better way of saying that.
