The beauties must strut the catwalk while embodying their geek's favourite London icon to impress guest judges Sonia Kruger and Jackie Frank. But they won't only be judged on their catwalk abilities; they'll also be judged on much they know about what they are representing - which ranges from the Queen to Big Ben. Meanwhile, the geeks are confronted with something unfamiliar: a naked woman. In this life-drawing challenge, the geeks believe they are being tested on their artistic skills but are in fact being quizzed on their ability to listen to women. Who will use their ears and not just their eyes to win the challenge?
