what youtube has been reduced to, attention whores seeking attention by stating the title of the video and putting "thumbs up if" in front of it. Its pathetic, that they do this, but even more pathetic are the people that actually thumbs them up.

Begging for thumbs up is disgusting and pathetic, it shows that you dont have your own opinion and are only commenting to get attention
