Focus on Alamo (sculpture) and explain the Pranks.
In June 2003, the Cube was the subject of a prank played by the ATF squad (All Too Flat) in which it was turned into a giant Rubik's Cube. The cube stayed up for about 24 hours before NYC maintenance removed the painted cardboard panels from the sculpture.
In March 2006, the Graffiti Research Lab distributed LED throwies to a group of people to throw onto and decorate the Cube.
In April 2006, a tub of chalk was left by the Cube and passersby began to draw on it.  Seven individuals were later arrested for vandalism.  The chalk was washed off by NYC maintenance the following morning.
In October 2011, the visual artist Olek (Agata Oleksiak) made a crochet covering with their signature camouflage pattern over the cube.
On December 14, 2011, Caltech students covered the cube in a fitted cloth, making it resemble the Weighted Companion Cube from the video game Portal.
In October 2013, a fake documentary video went viral claiming to show that a man lived inside the cube.
For Halloween 2015, a man dressed up as The Cube and stood in its place. At the time Alamo was temporarily off-site because Astor Place was being rebuilt.
