Pigeons - Weird Al Yankovic

Pigeons are such reprehensible things
Some critics, I'm told, call them rodents with wings
They terrorize folks with their constant dive-bombing
Which some find distasteful and some quite alarming
But still they fulfill an invaluable need
They give old men on park benches something to feed
In return for this honor, all they ask is that you
Allow them to soil the occasional statue
