You can also buy an apple, buy a mirror and spend 30 minutes eating in front of it. If you do it alone, at least you will enjoy the apple and putting funny faces meanwhile. If you do it in a park, putting a hat for money, some will call it street art. If you record it and put it on YouTube, lots will call you an asshole. But if you record it in 60's and your name is Warhol, it will be ART. It works with blowjobs, buildings, flat faces, kisses and probably eating your shit while playing a banjo.
