Vinesauce's Vinny is by far my favorite youtuber. First started watching his corruptions but then also got into his other stuff. We both laugh at incredibly stupid things, and a lot of my sense/style of humor was developed from his. Plus he seems like just an all-around likable dude. Plus I even ran into ShyGuyXXL on a stream one night!
Others I enjoy watching are Joel from Vinesauce (A.K.A. Swedish Vinny), pksparkxx, pixxeltrixx, dathings1 and Siivagunner. I'm sure there's more, but I can't think of them at the moment.
