You know, bros, I'm starting to think that Pewdie has a freaking wide vocal range. I remember his lower voices such as Stephano, the Irresponsible Dad, Badass Pewds, and Edgar (the one in his Dark Souls II LP, specifically), and then he has his higher voices, like the flare from Alien: Isolation and the Irresponsible Dad's kid...and then when I found out about him being in asdfmovie8, I honestly found it hard to distinguish his voice there (Seems like he voiced the alone-with-the-mirror gag, from what I've heard, but I'm still not sure). I also feel like his voice would probably be hard to identify if he really gets serious in voice acting, which I think that he doesn't do much in his Let's Plays. Anyway, don't you think that Pewdie has a very wide vocal range...? Ah, I also feel like more proof is needed for a lot of bros to say that PewDiePie has a freaking wide vocal range, too...
Do your best, have fun, keep calm, look at the bright side, and friendship for the win!
