The Best Episodes Directed By Richard Yee

Karl's doctor tells him he needs to get over Zoe and start dating again to cure his constipation, but he finds himself constantly saying the wrong things.

Karl Pilkington travels the world in search of answers to some of life's most important questions. He begins with marriage, wondering whether he is wrong about not wanting to tie the knot with his long-term girlfriend. In Delhi, he gains an insight into arranged marriages by going on a date with a prospective wife - and her parents - and in Bangalore, he is asked to help a pair of elite wedding planners. He also sniffs out a scientific approach to finding the perfect partner in LA, before searching for an alternative way of getting hitched in Las Vegas.

Why do people have children? That's the puzzler bothering world-weary philosopher Karl this week. Travelling the globe, he tries to understand why couples feel the need to become parents, visiting a fertility festival in Japan and a natural birthing centre in Bali - where he lends a hand with a delivery - and meets an LA couple looking to take the next step.

Karl ends his journey with a look at differing attitudes to death. He visits Ghana, where he shops for a customised coffin, before attending his first-ever funeral and the accompanying parade. He also meets members of a community in the Philippines who live and work with the deceased, is taught how to cry and deal with grief by a professional mourner in Taiwan, and returns to Britain where he creates a memorial. The last part of Karl Pilkington's Sky One travel show, set in the Philippines, has been pulled in the wake of Typhoon Haiyan.
