"Okay, docs. As you might have guesstimated, today we'll be talking about Newton's Third Law." Bugs rotated the white board about the vertical axis to reveal the following:

For every action, there is an equal and opposite reaction.

"What this means is that if I push you, you push me back. When I take a bite of this carrot," Bugs said, pulling a carrot out of his desk and chomping on it, "it's also pushing up against my teeth."

"Now this is easy enough to play with. If you're running in a panic - somebody's chasing you, or you just received startling news - you can run through walls. In cartoons, an equal and opposite reaction with the wall means that every part of you that comes in contact with said wall punches a clearly stamped hole."

"For example..." Bugs looked in his desk. He then panicked. "No carrots left? How will I get through class without any more carrots?! AHHHHHHHHH!" He then ran around the room a bit before taking a sharp turn and running through the wall into the hallway.

After two minutes, he reentered through the door and walked over to the hole. "As you can see, even my ears left a clearly defined hole in the wall when they should have folded back from the real world forces."

"Well, docs, you've got one more class with me. There won't be a final since I have no clue what you talked about the first bit of the semester, but I have some fun planned for Wednesday! Just you wait!"
