You troll : /
In case you are serious: Google Rickroll.

what???? no not this
im really serious

is it really from 2010 or just an older music clip that mTV played? I ask because it sounds like Last Goodbye from Jeff Buckley but its from the 90's. However Ive heard the song played in a show on Mtv not too long ago.
