Sydney: Australia captain Michael Clarke was momentarily stumped by a bungled question which appeared to be about his sex life as he celebrated Thursday's World Cup semi-final win over India.

Clarke, who had just led the co-hosts to a crushing 95-run win against the defending champions, was facing the media at the post-match press conference at the Sydney Cricket Ground, when he was asked to comment on "the tremendous sex" he had enjoyed since taking over as captain.
