In 1974 , while Niven was co-hosting the 46th Annual Oscars ceremony , a naked man appeared behind him , " streaking " across the stage . Niven responded " Is n't it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings ? " That same year , he hosted '' David Niven 's World '' for London Weekend Television , which profiled contemporary adventurers such as hang gliders , motorcyclists , and mountain climbers : it ran for 21 episodes . In 1975 , he narrated '' The Remarkable Rocket '' , a short animation based on a story by Oscar Wilde
