Tom Felton and Emma Watson may be friends IRL, but on-screen, it was an entirely different story for their "Harry Potter" counterparts Draco Malfoy and Hermione Granger.

Let's use the Time-Turner to take a trip down memory lane, shall we? In "Harry Potter and the Prisoner of Azkaban," Hermione socked Draco in the face in one of the most memorable -- and epic, TBH -- scenes the franchise has ever produced.

And even though the punch heard 'round the world happened more than a decade ago, Felton's ears are presumably still ringing from Emma Watson's fist. Speaking to The Huffington Post, the actor recalled the experience as "pretty hardcore."

"She’s got a mean right hook, that girl," Felton said. "It was originally a slap I think, so I said, 'Let’s test it out now. Give me a slap and try to work on it,' meaning give me a screen slap, a fake slap. But she actually smacked me on the face pretty hard, and I walked away from that rather listening impaired with my tail tucked between my legs."

And even though Malfoy totally deserved his comeuppance at the time, now that we know Felton is actually a -- gasp! -- Gryffindor, we kind of feel bad for the guy.

Having recently been wronged by the Sorting Hat, Felton put his own sorting skills to test when he was asked to sort a few celebrities into Hogwarts Houses. (It turns out, if Felton thinks you're a nice guy, you're Gryffindor material.)

Taylor Swift, Harry Styles, and Ariana Grande were all sorted into Gryffindor -- surely, Nearly Headless Nick will appreciate the smell of Swift's baked goods in the morning -- while Kim Kardashian and Miley Cyrus made Felton's list of Slytherins. As for Kanye West? Well, Felton surprisingly sorted him into Hufflepuff.Here's how we feel about that:
