Pigeons are dirty, and they casually carry around an array of fun diseases.
Pigeons regularly feast on garbage, hence the name "dumpster dove."
A pigeon's ideal last meal on earth after being placed on death row? A 3-day-old half-bitten, oxidized apple found underneath snotty napkins and ripped clothing at the bottom of a New York City trashcan.
Pigeons often stand atop their own kind for personal gain.
Pigeons often get too close to people that want absolutely nothing to do with their overbearing presence.
