The group were called individually into the Diary Room and seated behind a perspex box with two dots scribbled on it, which were placed at either end of two squiggly lines.
Housemates were told to draw a line connecting the dots, with a ten-second penalty occuring each time they go outside of the border or take the pen off the sheet. The person who completes the objective quickest will receive a "very special" reward tonight.
However, Big Brother decided to complicate matters by deploying a distraction that will knock housemates off their stride.
Alex Rose was sent a handsome butler serving from a chocolate fountain, Harry Blake received a sexy French maid cleaning the Diary Room, Jem Palmer got a gyrating disco dancer and Tom O'Connell had to ignore a fireman stripper.
Faye Palmer, meanwhile, had a clown blowing up and popping balloons, Jay McKray was given a sexy waitress serving his favourite trifle, Aaron Allard-Morgan faced a little boy armed with silly string and Louise Cliffe struggled with a topless fat man performing armpit farts.
Alex yesterday triumphed over her housemates in a rowing endurance task.
