Where are all the pigeons?

[Marsellus Wallace]

You lucky cunt.
I'm jealous. There are millions of the vermin here in London. They shit all over the place, it's disgusting. The only good thing about them is how I feel when I see someone kick one.
At work we used to have a Hawk that would come in a few mornings a week and kill a few, and it would scare some away. But the Hawk went mental one day, so we stopped using it.

LOL , how could a hawk go mental ?
