Ultimate Tak Ball is apparently a new team sport played with, among other things, contact stun guns. Guns & Ammo reports:
According to utblive.com, ... [t]here is a goal at each end of the field and each four man team attempts maneuver the 24-inch ball, reminiscent of a soccer ball on steroids, past their opponent’s defense and into the goal.... Ultimate Tak Ball players carry the over-sized ball en route to the goal.... [E]ach player is equipped with a shocking apparatus that can be used on the ball carrier in an eight-foot semicircular “shock zone” around each goal.
Thanks to Barnaby Zall for the pointer.
