A young man went to a lake for a swim but when he got there, he realised he had forgotten his swimming trunks.
Since there was nobody about, he decided to jump in naked. An hour later, he climbed out and was just about to get dressed when he saw two old ladies approaching.
He hastily grabbed a small bucket, held it over his privates and breathed a huge sigh of relief. But when the old ladies started to stare at hi, he felt decidedly awkward.
One said to him: “You know, I have a special gift. I can read minds. And I bet I can read yours.”
The young man scoffed: “So you reckon you know what I’m thinking, do you?”
“Yes,” she said. “Right now, I bet you think that the bucket you’re holding has a bottom.”
