What is up with those filthy stuffed animals stuck in the grills of the metal collector and garbage trucks? Are they used for bumpers? Are they showing off their best found objects? Are there gangs of truck drivers and that's how they identify themselves? The Daffy Duck Drivers vs the Roger Rabbit Roadies? Seriously, what's the deal? Every time I see one I want to pull them over and just ask. Seems like no one can put a finger on it. Thanks!
