YES. I love this series. Another good one is Sonic for Hire. Sonic Doing a bunch of odd jobs for other videogame characters like being sent by Mario to kill the Angry Birds and helping Kirby only to find out he's a serial killer (possibly my favorite)
As for youtubers Jacksfilms I think is very underrated. Sketch comedy like smosh but more Internet related things such a parodying Nyan Cat, and making fun of RWJ.
I also like Barats and Bereta similar to smosh but a dozen times funnier in my opinion because they don't have to resort to acting like retards in their videos like smosh has been doing.
I also like Ashens. A British guy doing funny reviews of usually awful technology. Bonus because he has the only 3D video on YouTube I know of (even if it's just a 30 minute loop).
331Erock. Guitar shreds over any song. Eg: Friday, Nyan Cat, castlevania.
