it's my life

The weather was very hot, so a guy desperately wants to take a dive in the nearby lake.
He didn't bring his swimming costume, but who cares? He was alone.
So, he undresses and gets into the water. After some delightful minutes of cool
swimming, a pair of old ladies walks onto the shore in his direction.
He panics, get out of the water and grabs an old bucket. As he holds the bucket in front of his privates he sighed with relief.
As the ladies get nearby they look at him and smile. Then one of them says,
"You know, I have a special gift, I can read minds."
"Impossible," says the embarrassed man, "You really know what I'm thinking?"
"Yes," the lady replies, "I know that you think that the bucket you're holding has a
bottom in it."
