This is how I imagine the task producers' discussions go:

Producer 1: "Right, lets think up a great task to get them to compete for housemate status!"
Producer 2: "Lets do something that will challenge them mentally and psychologically... something that will really keep the viewers entertained."
Producer 3: "I had an idea last night... how about a biscuit dunking contest?"
Producer 1: "THAT'S A BRILLIANT IDEA. Let's put that in to production!"

Ideally, that conversation would end with:

C4 Boss: "Biscuit dunking? You think BISCUIT DUNKING will keep viewers entertained? You have five minutes to say your goodbyes - you're fired!"

But seriously, BISCUIT DUNKING? Is that the best task they can come up with?
