Mark Parker —
10. The horse-eating bush in the pasture that he’s walked by 10 gazillion times.
9. A rabbit twitching one ear about 100 yards off.
8. The neighbor’s gone-mustang emu carousing through the brush.
7. A sudden sneeze from the person on his back.
6. His own tail on a windy day.
5. A prospective buyer.
4. Sugar overload — too much molasses.
3. The cell phone ringing in your pocket.
2. Saddle squeak.
1. Anything, man, anything at all if he’s in the mood.
