This morning on ESPN I saw the highlight of the LLWS umpire who was, along with the mascot, playing a guitar while hopping on one foot in a circle to the beat of the music.
That is one of the devices intentionally used by LL. It isn't just an umpire getting funky with a giant rodent. The whole purpose is to deflate the obvious tension that builds at one of these huge contests. They get the players dancing, the umpires dancing, the managers dancing, they bring out a little child to run the bases with the mascot, they do a lot to make the atmosphere more relaxed and fun. And I think they do a superior job.
