There were these three guys at the lake, a German, an Englishman and a Nigerian. The German took out his unit, put it in the water, waited a while and told the others, I can feel the water it\'s a 32 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 32.3 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 9 inches deep\'
