A young man and an old woman sit on a bench.
Near the benches walk a lot of pigeons.
Pigeons make a lot of noise.
Young man stands up and begins to shout: “Fuck off you stupid pigeons! Fuck off!”.
An old woman says: “Young man. You should be more pollite and not to say such a bad words.
You could just say “Shoo pigeons, shoo pigeons” and they will fuck off”.
