Degrees & Depth
"There were these three guys at the lake, a German, an Englishman and a Negro.The German took out his dick, put it in the water, waited a while and told the others: "I can feel the water it's a 24 degrees Celsius".
The other two were amazed. "Let me try", the Englishman said.
So he put his organ in the water, waited and said: "To be more exact, the temperature is 24.7 degrees Celsius".
At last the black man said, "Let me have a try". So he took his equipment, lowered it into the lake and said: "I've no idea about the temperature, but the water is 2 feet 6 inches deep".
