Omg, I adore PBG, PBG is the reason I got into JonTron and Game Grumps. XD
I had seen GG everywhere, but didn't care, then I started watching one of JonTron's videos but didn't care for that either. Then PBG's Zelda videos caught my eye, and I ended up watching every single video PBG had posted, then I needed something else to watch, so went back to Jon, since I was now really into the game reviews and stuff, and just fell so in love with him.
I've actually never seen one of his Game Grumps videos, really should though, but you're so cool X3 I've seen just about all of PBG's games, except for any to do with skyward sword, since I still haven't finished the game... lD If you like both of them, you should look into spacehamster! He's pretty funny, but a little less experienced at making videos then the other two, I still quite like his videos.
