Professor Pi

"Now, are there any questions for me? I'm Bat-Man."

- Professor Pi, Easy as Pi

Professor Pi (also known as Professor Pie, and as Chauncy Wiggles in Too Many Fruits) is Orange's substitute teacher and victim in the episode Easy as Pi. He was first seen teaching Orange, Pear, Midget Apple, Marshmallow, Beet, Cabbage, and Nectarine about fractions, when Orange had spit a seed at him. Soon after a sixth of him is cut out by Knife, making him lose his depth perception. He attempts to continue teaching, but another sixth of him is cut out, and he loses his short-term memory. The next slice took the left side of his brain, the side that holds his logic. The fourth slice took the other eye out, leaving him with only a third of his body left. Then the knife takes some of his tongue, giving him the disability to speak. Finally, the knife stabs the remaining sixth of Professor Pi, slamming him against the whiteboard before being taken away.
