Whether or not this is the biggest I'm not entirely sure, but I just find this to be the best story out of the bunch. In 7th grade my teacher did a Super-bowl pool. I don't know anything about football, or most sports for that matter, but I won $50 bucks! I think I put in 5 bucks altogether. Now, questioning whether or not 7th graders should be in a football pool is another story.
