<human>: Could you distill the essence of the text into 1-3 sentences?

Not my story, but a friend's father's.  I'll call him Billy-bob-joe.

Billy-bob-joe was trying to enjoy his son's choir concert.  (Not to toot my own horn or anything, but the choir performing that night was quite good ;) ).  Unfortunately, the two people in front of Billy-bob-joe didn't seem to understand "Please don't talk during performances."

During one part of the concert, a soloist sang a song and was doing quite well.  Any sane person would have been absolutely amazed by the singing and would have shut their traps.  But, sadly for Billy-bob-joe, the two twats sitting in front refused to quiet down.

As the concert drew to a close and the two jerkwads stood up to leave, our hero, Billy-bob-joe, had an idea.  As they stood, he took the gum from his mouth, and put it in the hood to one of their hoodies.
<bot>: Turdnuggets who refused to listen quietly and politely during choir concert probably got gum smeared all over their clothes after washing their sweaters.
