Stinging test for BB star Brian
Ultimate Big Brother housemate Brian Dowling had to plunge his hands into a pile of nettles in a bid to win contestants a party for the evening.
During today's tasks housemates had to complete a series of uncomfortable challenges without making a sound.
When Brian entered the task room he was ordered by Big Brother to find a "needle in a nettle stack" in three minutes.
The former cabin crew supervisor for Ryanair pulled off his hat in frustration and screamed when the three minutes was up.
The 32-year-old, who won the show in 2001, is the bookies favourite to win the series. Bookmakers William Hill have him priced at 2/5.
During other silent tasks, Michelle Bass was tickled by Big Brother 4 housemate Jon Tickle, Vanessa Feltz and Chantelle Houghton played catch with a cactus and "nasty" Nick Bateman crawled across 300 upturned hairbrushes.
After all housemates successfully kept their mouths closed during the challenges they were rewarded with a rock party.
The contestants were given costumes, blow-up guitars, food and alcohol as a reward.
