Minecraft wiki entry for Easter_eggs, associated text: In the texture for the armor stand, in an unused area in the bottom right, the word "Searge" can be seen in a black box. This is presumably put there as a signature by Searge, the developer that implemented armor stands. In the bottom left, the word "Jappa" can be seen. This is likely another signature, this time from the texture artist, Jappa, who was in charge of the Texture Update.
