HAHAHa this is funny… The man is surely smart but why he did say initially there is no one in the house?!!! I still thinking about this point ! hmmm well does he intended to say No to act like what he acted at the end !!
Since the policeman asked if there was someone (he meant burglars) in the man's house, the man replied like that. Actually, the burglars were in the shed, not in the house. Thanks for a very funny story.
