Dellwether

This sweet old lady was walking up 3rd Avenue past 93rd Street today when I saw her turn the corner and beat the shit out of Jeff Jarvis.

UPDATE: Let's step back and turn to Wikipedia for the 10,000 foot view. The term bellwether originates from the middle English bellewether, and refers to the practice of using a castrated ram (or "wether") with a bell around his neck to lead a flock of sheep.
