I stumbled accross one of sxephil's movies but I vaguely remember that I didn't like it.

I watch a lot of German youtubers like Albertoson.

The only US-youtuber I know is ClaytonCubbit who made the awesome hysterical literature videos

I don't watch youtube.. I did watch a few of Jenna Marbles videos... she's funny at first.. but then it just starts getting stupid.. in my opinion.
