Operation.

Fooled you!  No Operation here silly. But remember this gem

Hours of laughter (and just a few small tears) were all ours this evening because of this fun little game that has the most annoying sound you'll ever here when metal touches metal.  It's almost shocking how annoying it is.  But...we got through it and laughed as we tried our hardest to never hear the sound.  Addi was pleased as punch with herself because by the end of the night she was able to pull the rubberband off all by herself.
