On one episode of Harry Hill's TV Burp, there's a lost ITV1 ident spoof which featured a fake Sian Lloyd, who is holding her sign that reads "I'm Sian Lloyd" in the blue and yellow set from the channel's idents from September 1, 2003.
It has now been found alongside Fern and the others via the Season 2 episodes of TV Burp available online.
