Here's a first look at the Big Brother 2013 housemates tackling this week's bizarre countdown task.
Yesterday Big Brother set the group their third shopping challenge of the series, and the 5...4...3...2...1 task is typical BB.
The challenge is comprised of five tasks numbered 5 to 1, with each number representing the amount of housemates required to take part in the task.
Last night saw the first two tasks, starting with Task 5 which required the 5 Unhealthiest housemates.
Sophie, the twins, Hazel and Wolfy put themselves forward for what turned out to be a rather messy task. The group first had to fill bowls attached to the top of their heads with gunge by pumping giant balls which they were sitting on.
Once the bowls were full, they had to transfer the gunge to a measuring jug and accumulate enough gunge to pass the task in the time limit.
Later on and the four smartest housemates - Dan, Jackie, Callum and One of the twins (we're not going to lie, we've not a clue) - took on the Fourth task. Stirring Big Brother repeated bitchy lines that had been said in the house, with the four smartest housemates having to fill in the missing four letter word by spelling it out using their bodies.
