A man and a women walk into a bar and order a drink for every person in the bar. They are very happy.When the bar-tender asks them why they are so happy, they reply: 'We finished a jigsaw puzzle in only two months'.

'Two months?' the bar-tender exclaimed, 'it's not supposed to take that long.'

'That's not true,' said the woman, 'it said 2 to 4 years on the box.'
