When Big Brother came back to our screens for a seventh series in 2006, one of the contestants had a very memorable entrance to the house.That was Glyn Wise, who, at the time, was an 18-year-old lifeguard wearing only a pair of swimming shorts, hoping to channel the David Hasselhoff look. As he walked past the crowd and made his way into the house, he had a mixture of cheers and boos, the same as the other 21 participants from that series.
