Hilarious jokes-Finding a race winner

A rich racehorse businessman calls for the services of a geneticist, a physiologist and a physicist. He told them he would award a million dollars to the one who could accurately identify race-winning horses. After several weeks of working on the horses, they were ready with their conclusions to be reported to the billionaire.

The geneticist reported, "I've considered all the current genetic research, checked blood-lines going back several decades, but there are just too many behavioral and environmental factors to arrive at a definite conclusion."

The physiologist reported, "I've checked muscle mass, bone volume and density, and all the other factors I can think of, but it seems to be too complex. It is too difficult to predict a winner."

Finally, it is the physicist's turn who seems to be very relaxed and reports while handing an index card to the billionaire. "There you are," he says "I've found an equation that can identify a winning horse."

"Great!" exclaims the billionaire, "Do you want cheque or cash?"

"Err...there's one little thing that you should know," said the physicist. "It only works for a spherically symmetric horse running in a vacuum."
