Day 19: The Boys versus Girls task
2 hours ago
It's a battle of the sexes as boys are set to be pitted against the girls. Big Brother wants to determine who's better: male or female?

Because there are only three girls, it's going to fall to Razor to pick up the slack. He'll become an honorary girl and join the girls' team for the day. He's already dressed for the part.

For the first task, one member of each team will take part in a multi-tasking obstacle course in the garden. They'll race to park a car, get some shopping and a baby out of the car, answer a phone and carry it with them, put their shopping on some shelves, down a drink, change their baby’s outfit and nappy and then, after gathering their breath and bearings, they'll put the baby into cot.

Later in the day their second task is a maths quiz. Razor and Rylan will each do a maths quiz in the Diary Room, watched by the other housemates - but how will they cope with the distraction of a female and male stripper respectively?

In the third task, all housemates will don sweat suits and have an hour to exert themselves in the pursuit of perspiration. The team which gathers the most sweat in their time will come out on top.

It's going to be a busy day indeed. By the end of it, using science, we'll have accurately figured out who rules the most. Boys or girls. Who's it going to be?
