An Englishman, a Welshman and a cyclist are all asked to take part in a psychological evaluation.
Each is given two identical rubber balls and asked to spend one minute evaluating them in an empty eight foot square room.
After the third man has concluded his minute, all three are lined up and asked to describe what they found out about the behaviour of the rubber balls.
The Englishman says, "I found that if you hold a ball in each hand and throw them towards the floor in front of you at approximately 45 degrees, at exactly the same time, they bounce off the floor, onto the wall in front, onto the ceiling above you, then onto the wall behind you, the floor behind you and then back into your hands."
"Very good!" said the examiner.
He then asks the same of the Welshman, who answers, "I also found that if you hold the balls, one in each hand, but throw them in opposite directions in front and behind you at an angle of 45 degrees at exactly the same time, they bounce on the floor in front and behind you, the wall in front and behind you, the ceiling above you, the wall in front and behind you, the floor in front and behind you and then finally back into your open hands, at exactly the same time."
"Excellent!" said the examiner.
Then he turned to the cyclist and said, "What did your test reveal?"
"Not much", said the cyclist. "I lost one and broke the other."
