Blockaphobia
There was one where we had to use blocks that were red on one side of the cube, white on the opposite side and diagonally divided between red and white on the four remaining sides to reproduce random patterns that the guy made and then destroyed. That flipped Larry out. When it was his turn to do this test he got so upset that he started throwing the blocks and two cops were called up from the jail area to drag him out into the hall and calm the little freak down.
