Temptation Island (UK)
Synopsis
Based on the US show of the same name, Temptation Island took couples, seperated them and placed them in the company of lots of gorgeous members of the opposite sex for a few weeks and saw whether they'd stay faithful to their partner. Each episode had a "bonfire ritual", where contestants got to see what their partners had been up to recently with hilarious and not-so-hilarious consequences.
Whilst originally shown on Sky One, this was repeated on Channel 4.
