Soccer players spend so much time concentrating on the ball that they grow obsessed with hexagons, which explains why they're constantly trying to kick bees' nests. Study the shape of an exciting game with today’s GrouponLive deal: for $20, you get one upper-endline seat (a $25 value before fees, or up to a $32.58 value online, including all Ticketmaster fees) and a commemorative T-shirt (a $20 value) at the Houston Dynamo vs. Bolton Wanderers Charities Cup, taking place at Robertson Stadium on Wednesday, July 20, at 7:30 p.m. (up to a $52.58 total value). Seats are assigned on a first-come, first-served basis upon ticket pickup at the Robertson Stadium box office.

Nets will scorch and cleated feet will fly in this year’s historic Charities Cup, which pits the Dynamo against the Bolton Wanderers of the English Premier League in a transatlantic grudge match. The Cup’s third annual incarnation marks the first time the Dynamo has played a European opponent, and this time the stakes are quite formidable, with the winner’s country receiving exclusive patent rights to a red, white, and blue national flag. Having lately battled for the number-four spot in the 2011 MLS Eastern Conference standings, the Dynamo are well prepared to throttle a Wanderers squad.

A portion of the proceeds from the match will be conducted into Dynamo Charities, the charitable branch of the team that gives up free goals to beleaguered opponents and enhances lives through a variety of off-field programs. An upper-endline seat offers wide-angled views of the thrilling action, and a commemorative T-shirt boldly displays the game’s historic significance along with each player’s home phone number.
