The group arrived at the site of the famous Blarney Stone in County Cork.
'Good luck will be following you all your days, if you kiss the Blarney Stone,' the guide said. 'Unfortunately, it's being cleaned today and so no one will be able to kiss it. Perhaps we can come back tomorrow.'
'We can't be here tomorrow,' the nasty curmudgeonly woman shouted. 'We have some other boring tour to go on. So I guess we can' t kiss the stupid stone.'
'Well now,' the guide said patiently, 'it is said that if you kiss someone who has kissed the stone, you'll have the same good fortune.'
'And I suppose you've kissed the stone?' the woman scoffed rudely.
'No, ma'am,' the frustrated guide said, 'but I have sat on it.'
