All contestants are sent to cooking school for one week before starting

Just letting all you manipulated viewers know, each team is sent to a cooking school for one whole week, all day every day. The editors and producers prepare a script for each house/episode, they sit with each contestant and tell them what is expected of them. For example: "Okay Team A, you are the villains, you need to spit out insults and make yourself hated, Team B, you need to be charming and quiet, you're the team most people like, Team C, you're the hot team so you need to act like aussie tradies and flirt with the young girls and create fake romances" and etc etc. Pete and Manu don't care because they receive a big fat check. They know who is going to win once everybody has cooked so they start manipulating the scores to suit their intentions. They primarily focus on the drama and not the food (all you idiots should see this evidently). Teams are selected by categories, the producers want variety for entertainment, they are not selected by their talent in cooking (ironic isn't it?), they will normally search for a gay team, a family team, hot guys team, a team with elderly people, and a couple of teams with your average couples to avoid suspicion of this very fact.

Have fun watching THEIR (producers) Kitchen Rules!
