Okay, I'm going to list them all... Let's see...
Smacktalks: This guy's a pimp. He be showin' yo creations on his channel, and makin' you popular in the WWE Games Community. Plus, him just talking is absolutely fantastic.
Total Biscuit: He's hilarious, and makes nice long videos that I can actually full screen-inize and enjoy. Plus, his voice reminds me of Wade Barrett. <3
Shane Dawson: He's ghetto, yo. He's one of us. He's everything I want to be on YouTube. Just being me. Oh, and I also want candy, but that's a different story for a different time.
TeemingTubbyEmu: I really don't know why I watch him. He seems like a real jerk sometimes, yet I just can't... Stop...
Sinc: He's hilarious as well. I can definitely relate to him more than any other YouTuber. Entertainment for days.
Vahnchand: They're very funny as well. Plus, I like Vicboss' wrestling promos he does every now and then.
greenyxi: His vlogs are funny in a very cringe-worthy way. He makes them enjoyable though. Plus, he makes a f*ckton of Let's Plays, which are useless to me unless he's doing a Final Fantasy. >_> He's also one of my best friends.
I believe that's it. For now at least. If I remember any later, I'll come back and edit this post to add them in.
