The challenge this week is based on International Joke Day. The housemates will be given five tasks themed on classic joke formats.
The five formats are: 'An Englishman, an Irishman and a Scotsman', 'Why did the chicken cross the road?', 'A nun, Scouser, doctor, waiter and mother-in-law', 'A dumb blonde' and a stand up routine.
Big Brother told the three nominated housemates - Sunshine, Caoimhe and Shabby - that they will be playing the Englishman, Irishman and Scotsman but the rest of the positions could be decided among themselves.
The Tree of Temptation told Ben he had to make sure he took the part of the stand-up in the task, so he quickly volunteered for the position and the rest of the housemates distributed the parts between them.
John James and David will be chickens, Josie will be the dumb blonde and Ife, Mario, Corin, Steve and Nathan will be playing the nun, Scouser, doctor, waiter and mother-in-law parts respectively.
