Can anything really be art?

According to Andy Willow who is known for his Brillo Boxes piece of art, he believes that anything can be considered art.  Depending on the individual looking at the piece, they can consider just about anything to really be art.  For example, Damien Hirst has a Shark in a glass box at the Met and many people consider that to be art. But isn't it really just a dead shark being displayed?  To some people that may be true but to others it may not.  Art is something that brings attentiveness from people and catches the eye of people even when they are not really looking.  It is something that some people perceive to be beautiful, ugly, interesting or fun.  In my opinion it really has to deal with the individuals idea of what is art and what it isn't.
