Scientists are still puzzled by the contents of the modern basketball and believe it to be filled either with helium or several baseballs. Contemplate this conundrum with today's Groupon: for $12, you get an upper-level end ticket to a Stanford men's basketball game against the Yale Bulldogs at Maples Pavilion on Tuesday, December 28, 2010, at 7 p.m. (a $22 value).

Backed by the all-around skilled play of Jeremy Green, Josh Owens, Dwight Powell, and the rest of Stanford's hard-court heroes, the Cardinal are poised to make a winning run this season. Coach Johnny Dawkins has his squadron of playmakers in prime shape to dazzle the crowd and destroy Yale. Their fast-paced attacks and cunning stratagems will cut through the Bulldog defense with the cold-blooded precision of scissors through a polyester net or sleeping supervisor's comb-over. From the upper-level end seating in sections 6–8 and 14–16, fans can watch the Cardinal dribble, pass, and toe-dunk amid the electrifying atmosphere of Maples Pavilion while snacking on an item from concessions or doing the wave every time the stadium fills with water.
