I think it's simply a kind of humor you either really like or totally dislike... =/
And which side you're going to choose on how you feel about "SMOSH" is probably being narowed down to either your age, your preference or your mood/state of mind while watching a video... or all of the above of course!
I simply couldn't be triggered to raise a corner of my mouth when watching some videos, probably because I'm too old for this *blank*, I'm not into the humor displayed (slash off a head by a zombie and I'm back in the game!) and I actualy was feeling good when I started to watch, but my thermostat dropped to "freezing" when I was finished with it... that's all! =D
I would of gone like that if a spider came down on me,I'd flip out.Anyways,I also really like Smosh and there videos,especially The Legend of Zelda Rap and all of their Food Battles
