A few years ago, England cricket fans began singing at one of the Australian bowlers, to the tune of The Sloop John B (the bit about drinking all night):

He swings to the left
He swings to the ri-i-ight
That Mitchell Johnson
His bowling is shite

Of course, by the next series Johnson’s bowling had improved no end and he was taking England wickets in delivery after delivery, so they stopped singing it. But it was such fun to sing that lots of others – particularly football crowds – would take it up, by making a slight alteration to the words wherever appropriate. My favourite was at a Preston North End match:

We don’t know the words
We don’t know the wo-o-ords
We’re Preston North End
We don’t know the words.
