Oh, POO, I love this video. I click on this every time I feel like listening to HBFS on YouTube, which is almost every day, although I have an MP3 of this song.
At first I was like WTH? Some guy moving his hands to a song?! Then I fast-forwarded it a little. That was one of the weirdest and funniest things I've ever seen. (I must say the video being one of my favorite songs, made it even better.) Whoever thought of that had to be a psycho.
