Mad Hatterbot

Mad Hatterbot is a robot at the HAL Institute, he is based on the Mad Hatter from Alice's Adventures in Wonderland. The Mad Hatterbot's only line is "change places!", which interestingly all the robots at the HAL Institute seem to comply with, including the doctors and nurses.

Quotes

 * Mad Hatterbot: CHANGE PLACES!
 * Dr. Perceptron: I forgot we had changed places. Mad Hatterbot: CHANGE PLACES?!

Appearances
In Alice's Adventures in Wonderland, the label on the Mad Hatters hat says 10/6, but Mad Hatterbot's says 5/3, which is clearly just the most efficeint (robotic) expression for 10/6.
