PigeonCam (TM)

High on a ledge the winged rat sits
Sphincter clenched
Surveying the rushing hordes
Awaiting the perfect target
The one who stops
To look at the fountain
In his nice clean shiny red coat

Sphincter relaxed the winged rat swoops
Another day ruined
His job here is done

then its off to reload on that tramp sick he spotted earlier...

Big drop
