My first favorite video originated on Tosh.0. and shows a young girl around 3-4 years of age, trying to take her bowl to the sink after eating. I was in stitches watching this video!
I just was shown the coolest music video of the group "Walk Off the Earth", which is five people playing on one guitar (all five were doing something on the guitar at the same time) and they also sang with the song. It is the song "Somebody that I used to Know" by Gotye.
