Funny how one thing leads to another (which used to be my favourite chat-up line in another life)
A prize cockerel got so quick at his job that the farmer decided to increase   his stock of hens - the more he bought, the quicker the cock got
Eventully his field was crammed full of hens to be 'trod'
The farmer got up one morning to to find his hens all done by just after breakfast, bur the cock was lying face down in the corner, wings outsread with a flock of predatory hawks circling over head
Panicking at the thought of losing such a valuable bird he leapt the fence and ran to the prone cock, who hissed ot of the side of his beak "Feck off and let them land, you stupid git"
