The nuclear family, unlike the family powered by teamwork, spends its free time spinning around the same giant reactor. Reenergize your amusement with today's Groupon: for $350, you get a three-hour softball or kickball team-building party for 20 people at Arena Softball in Roseville (a $715 value).

Arena Softball brings peers together with fun team-building parties held in an all-inclusive atmosphere. During the party, groups will go head-to-head in one game of arena softball or kickball in which every member will have the chance to participate and inhale their fill of oxygen. Teams also have access to a fully equipped multimedia meeting room for three hours, as well as three batting cages exclusively rented for one hour. Each indoor cage is built in an open style so that batters can watch the trajectory of their baseballs or softballs, while built-in speed and placement variations assure that heavy hitters don't expect uniform pitches from uniform-wearing automatons come game-time. After the scores are tabulated, athletes can replace lost electrolytes and chances at glory with a menu of tri-tip beef sandwiches, salad, chips, and fountain beverages.
