A man walks into a pub and the place is deserted, so he stands by the bar waiting to be served. After a moment he hears a voice,
'Those are very nice trousers you're wearing, sir.'
But when he looks round he can't see where the voice came from. After another short while he hears the voice again,
'And the shirt really makes you look quite handsome.'
Before the man can work out who is saying all this the barman appears behind the bar, carrying a crate up from the cellar.
'Was that you talking about my clothes just then?' the man asked.
'No sir, that'll be the peanuts - they're complimentary...'
