Sketchers After Shooter

When the school shooter leaves your classroom and the autistic kid’s sketchers light up.

Explanation

The humor comes from the unexpected and dark twist. The joke sets up a dangerous scenario with a school shooter and then pivots to the seemingly random detail of a child's light-up shoes, implying that the child's movement triggered the lights, thus indicating danger. It's funny because the focus shifts from the extreme threat of a school shooter to the trivial detail of the shoes, making a morbid situation more absurd.
