Cute story, rainmaker.
At the site where i did pro games during the summer, they also have a high school and college league with games prior to the pros on many of the game days. since the gym is a converted church building, locker room space is very scarce, so the officials put their bags under the scorer's table.
As a result, it's quite common to hear beeping, ringing, and (depending on how the bag is packed), vibrating against the bleacher the bag is sitting on.
Would be curious to see an official's reaction if they inquired about the cell phone, only to be told it was either theirs or one of thier partner's phones making the noise.
