Thee are many, many videos on YouTube by these guys. They are all hilarious; it was a serendipitous moment when I first discovered them.
In case you haven't heard of them, they have published masterpieces such as the Chad Vader saga (a must see), the Morning Talk Show Mysteries (not as good), and many more. Their most recent video was "We Replaced This Man's Coffee With..."
Tell us what your favorite video from them is.
Mine has to be their Chad Vader saga.
EDIT: I also prefer the "We REplaced This Man's Coffee With.." video.
