'First past the post' is explained through teenagers going for a meal at a pizza restaurant. The friends make their individual choices from the menu. But everyone in the group is then served the same pizza topping - the one chosen by most teenagers. Proportionality is then explained through serving additional pizzas to the teenagers who had wanted other toppings. Through the use of graphics, and based on the 2005 General Election results, viewers are shown how seats were divided between political parties under first past the post and how the share of seats might have been different under a simple proportional system.
