little fuckers

I have a jar of little fuckers.

All of us collect them.

They live in gutters, on the streets, and under the foliage.
They make their way into our rubber and slow us down. 
They ruin our races, our rides and our commutes.
Little fuckers are any material foreign to a bicycle tire that causes a puncture.
Collected, photographed, and viewed on high definition monitors the details and textures of the little fuckers would be dramatic. When the viewer approached the monitor for a closer look a proximity sensor triggers the monitor to show a tiny image of the little fucker. This inturn steals the opportunity for closer inspection.
