Ancient Greeks celebrated sports such as gymnastics, wrestling, and running around wildly with an open flame. Honor athletic history safely with today's Groupon: for $30, you get a 10-week spring league registration from Dodgeball is Life (up to a $62 value). The season begins March 20, and matches are held at the Ocean Beach Recreational Center.

Created for love of the sport by six stalwart enthusiasts, Dodgeball is Life runs seasonal leagues that pit five or more teams against each other, with members of all skill levels and both genders taking to the court. Players receive their team assignment from the league, joining court-ready crews typically composed of five men, two women, and one taxidermied mascot. The season pits these impromptu groups against each other in eight or more chuck fests, which lead directly into playoffs for the top-performing teams, which will get to replay grudge matches or continue to demonstrate their immunity to rubber. All matches take place on the squeaky courts of the Ocean Beach Recreational Center, beginning at 7 p.m. and usually concluding with a trip to a local bar to celebrate camaraderie over a brew.
