Race horsing may be "The Sport of Kings" and boxing is sometimes called "The Sweet Science," but modern Science Kings want a sport they can take into their own hands without risk of trampling death or unseemly nose quashing. Today's Groupon satisfies the athletic desires of Science Kings: for $40, you get two Blue Sky Golf Passes, each of which is good for discounted rates at the area's top courses, on professional instruction, and on golf equipment. The retail value for one card is $99, but if you use it to its full potential, you can get up to $2,000 worth of freebies and savings. The pass is valid until December 31, 2010.

From Chase Oaks Golf Club to Tour 18 Dallas, you'll have the opportunity to putt and play at discounted rates on 27 of the region's greatest greens. Dress codes, dates, and rates vary per course. Other game-changers include golf lessons and training, such as a one-on-one lesson using JVC video from Edwin Watts Learning Center (a $49 value).

Expect to receive your pass within seven business days of submitting your mailing address. This Groupon is not valid at Champps or Hooters.
