The weather was very hot, so this man wanted desperately take a dive in the nearby lake. He didn't bring his swimming outfit, but who cared ? He was all alone. So he undressed and got into the water. After some delightful minutes of cool swimming, a pair of old ladies walked onto the shore in his direction.
He panicked, got out of the water and grabbed a bucket, which laid on the sandy beach. He held the bucket in front of his private parts and sighed with relief.
The ladies got nearby and looked at him. He felt awkward and wanted to move. Then one of the ladies said: 'You know , I have a special gift, I can read minds.'

'Impossible', said the embarrassed man, ' You really know what I think?''Yes', the lady replied, 'I know that you think that the bucket you're holding has a bottom in it.'
