The housemates spent much of Wednesday night discussing one of their favourite topics - sex.
As the group got tipsy on cider, Helen posed the explosive question: "Has anyone been in a nightclub and done it in a toilet?"
There followed a brief calm as the housemates all racked their brains, before Brian piped up, "I have."
The shock revelation was enough to silence even boisterous Helen, as the demur Irishman recounted his audacious tale.
"I was in this bar and met this guy who bought me a drink," he began. "I went to the toilet and when I came out of the cubicle he was there.
"I was like, 'OK'. He went to kiss me and pushed me into the toilet. There was no sex, but there was an act committed," Brian finished.
Brian's outlandish story prompted a outburst of 'odd sex' stories, with Paul asking the old classic: "Where's the weirdest place you've ever had sex?"
The poser of the question admitted to enjoying carnal pleasures in the back row of a crowded cinema, while Elizabeth caused a few raised eyebrows with her story of times past.
"It was with this guy," the diminutive individual divulged. "[We did it] on the lawn in front of their [his parents] window, with a full moon."
Revealingly, Helen did suggest having sex on TV would be the strangest place.
And Paul's response of, "I couldn't," was perhaps the most eye-opening statement of all during the group's sex talk.
Big Brother 2 is a Bazal production for Channel 4.
Strange sex!
