These four muggles took the sorting hat quiz on Pottermore to see what house they would end up in at Hogwarts. Taking an online quiz on a laptop is only slightly less magical than having a sentient hat that reads your mind when placed upon your head.
For those who did not receive their much anticipated Hogwarts acceptance letter when they were 11-years-old, J.K. Rowling's interactive website Pottermore allows you to take a really long, in depth quiz in order to find out what Hogwarts house you most belong in. Rupert Grint, Bonnie Wright, Matthew Lewis, Evanna Lynch (Ron Weasley, Ginny Weasley, Neville Longbottom, and Luna Lovegood, respectively), are among the few who muggles who, in a way, actually got to go to Hogwarts. And yet 75% of them got sorted into houses different than the ones their characters did in the films.
If you put on an old witch hat from a Halloween costume and squint your eyes really hard, you can almost convince yourself that you are in the great hall being sorted and not on your computer pretending like a nerd. Just make sure you're doing that in your own home and not at a Starbucks or something, you weirdo.
