It's been a pretty horrible week in music when it comes to songs going viral. Rebecca Black started it off with possibly the worst video of all time with "Friday." Now, a 13 year old named Zack has decided to throw us a curve ball with his Bar Mitzvah music video, "I'm Zack."

Take a look at both videos and let us know which is the worst. Both a equally bad. The sad thing is that both are trying to be serious about the music. Just hurts.
