Man Utd had variations of this that made me chuckle when I first heard them.
Man Utd
Park, park, wherever you may be,
you eat dog in your own country,
but it could be worse,
you could be scouse,
eating rats in your council house
Liverpool responded with
Dirk Kuyt,
Wherever you may be,
You smoke dope in your home country.
But it could be worse,
You could be Manc,
Asking your sister up for a w**k!
