Johan Lorbeer is a German street performer. He became famous in the past few years because of his "Still-Life" Performances, which took place in the public area. His installations includes "Proletarian Mural" and "Tarzan", which are famous in Germany. Several of these performances feature Lorbeer in an apparently impossible position.
On May 14, 2008, an Azande high court accused Lorbeer of practicing witchcraft. The basis of this accusation is a recently published metareview, which compiled and analyzed the data concerning rates of impotence among his male (and German female) audiences. Thus, he has cancelled his plans to perform his "Thinker" pose while perched atop a pregnant white rhino.
Although this trick seems genuine, it is not magic. He manages these positions by hiding his actual arm under his clothing and the 'arm' that is seen sticking to the wall is a support bar.
Here’s a little clue on the trick; His arm is the supporting bar, and his real arm is hide inside his cloth.
