Disc dog, or Frisbee dog, is a sport that showcases speedy, high-flying dogs catching discs thrown by their human teammates. It got its start in the early 1970s, but its popularity was boosted in 1974, when 19-year-old college student Alex Stein ran onto the field during a nationally broadcast baseball game and began throwing discs to his dog, Ashley Whippet. The game was stopped, and the pair proceeded to entertain the crowd for how long before Stein was escorted off the field and arrested? Discuss
