There are very few "Harry Potter" questions that Daniel Radcliffe hasn't been asked.

However, during his "Ask Me Anything" session on Reddit, one fan managed to pose a query that Radcliffe hadn't heard before: "If you had a Horcrux, what would it be?"

"Um... that's a really good question. First of all, congratulations to you for asking me a Harry Potter question I have NEVER been asked before, that is not easily achieved!" he wrote. "I would say... I was gonna say my iPod, prolly put it in that, but I would put it inside an album on the iPod, so you'd have to open that album. So I somehow want it to be connected to a particular album that means something, like Ziggy Stardust. So that's how I'd want to do that."

For those not familiar with the franchise, a horcrux is an object to which a "Harry Potter" character can attach his or her soul.

The actor, now 25, also answered a few other "Harry Potter" questions for fans, including the following.

Harry Potter is obviously a Gryffindor, but what is Daniel Radcliffe? I mean, I... to me, it's not a... to me I absolutely think I would be in Gryffindor! But there's never any doubt of that for me. Yeah. I like, maybe I'm just biased because I played one for so long, but I could never picture myself in any other colours.

Assuming you read all the Potter books before their respective films were made, did you ever get upset about changes or omissions from the stories when you were reading your script? Ehm - not particularly. I think we had very quickly become aware that stuff was not going to be in all the films that we couldn't fit everything in, I think I remember the thing early on that me, Emma and Rupert were all slightly surprised by, that we had all ABSOLUTELY LOVED the chapter in the Chamber of Secrets book about the - I think was it Nearly Headless Nick's Birthday Party? But I think it was some sort of a ghost birthday party that was not in the films, and I remember at the time we were all quite surprised by that. I know some people would have been quite happy to see a 4 hour long Harry Potter movie with every detail in there, but some people also would not have...

Daniel, did you put your name into the goblet of fire?!?!?! You know what, I don't think we did I'm pretty sure. Because I think that by that point, they had figured out my handwriting was so bad that they would never let it be seen in the film. So I'm pretty sure one of the props guys wrote "Harry Potter" neatly on a piece of paper for me to put in.

When you auditioned for your role in harry potter did you have any idea that it would turn out to be this major of a movie series? Not really. Even as a kid, I hadn't the full scope of the Harry Potter phenomenon, hadn't really, ever, made an impression on me I guess? Obviously I'd read the first couple of books, but I wasn't as into it as a lot of my class was, so no, I could never have imagined it was as big as it was. I think maybe it's only now that I'm really starting to get a fuller sense of how wide-reaching it was, and how many people's lives it affected, which is very cool.

What was your favorite scene to do from the Harry Potter movies? Yeah... favourite scene to film... god... that is a really hard question, to pick just one... the first thing that comes to mind, and it's a silly one, but doing all the Gringott's stuff in the last movie with Rupert and Helena and Warwick and Emma, that was like a really fun time. We were all enjoying ourselves in that, it's an action sequence so it was quite, it was more of a technical challenge than an emotional one, so it was a lot of fun to get right.

Not including Harry Potter, who is your favorite character in the Harry Potter franchise? Probably Sirius. Like I always loved the character, and then Gary's portrayal of him I thought was perfect. Or Lupin, really. Any of the characters my dad used to hang out with, other than Wormtail. There was always something bout those two guys I loved a lot.

Daniel, did you keep anything from the set of Harry Potter? Oh yeah, of course. I wasn't going to leave there without grabbing a set of glasses!

What was the best prank you pulled on the HP set? God... I should probably about the one that was pulled on ME, rather than any I pulled. Because it came from a very unexpected place. There's - in the 3rd film - there's a shot in the great hall of all the kids sleeping in the great hall, and the camera starts very very wide, and comes in so that it's an inch from my face, a very long developing set, yeah, and Alan Rickman decided he would plant one of those fart machines in my, uh, sleeping bag, and they waited until like -the camera had come in for this huge DRAMATIC developing shot, and then unleashed this tremendous noise in the great hall. I immediately thought: "This is one of the other kids fucking around, and we were going to get in trouble." But as it turns out, it was one of the members of Britain's acting royalty. I think I laughed a lot, was probably a bit embarrassed, but it was really really funny.
