Political Cartoons

In my high school physics class, I had a teacher who was a firm believer that any problem - trajectory, acceleration, anything - was made better by the addition of a pterodactyl. To reinforce this point, he would occasionally act out a pterodactyl, starting at one end of the room making huge arm flapping motions, high stepping, and screeching by inhaling. It was all pretty effective at getting us to ba attention, but he stopped doing that when, after a particularly agressive screech one day, his eyes glazed over, his face went purple, and he sat down on the floor - pterodactyls will fuck you up, apparently.
