Big Brother challenged the 16 housemates to not laugh for two whole days in the house, while setting up treats and surprises that made the task extra difficult.

A Megalols comedy club gig was set up featuring comics such as Keith Harris & Orville, while the famous Big Brother electrocution suits were also brought back in an attempt to break the housemates' resolve.
However, across the days, the housemates only had 19 fails. Their number was well below Big Brother's maximum of 25, meaning they win a luxury shopping budget this week.
As a reward for their efforts on the task, Big Brother also gave them pizzas and beers to celebrate.
The housemates screamed and jumped on the sofas when the results were revealed. Luke S jumped on the shoulders of Arron Lowe and Conor, while Chris Mcintyre ended up ripping off his shirt in jubilation.
Big Brother continues every night on Channel 5.
