Other things to do with it: You can 'shake hands with the unemployed', or 'point Percy at the porcelain', when nature calls.
One can 'whip one's dummy', or 'flog the bishop' (in deference to 'Spaw).

That foamy liquid that invariably ends up in the toilet bowl after one's call of nature, has been often referred to in my neck of the woods as 'a bishop's collar'.

Having sex can be described as 'burying the baldy fella', 'playing hide the sausage', or indeed being 'up to me balls in beef', to be more obtuse.
The Irish language has us 'ag bualadh craiceann' - beating skin - and who am I to argue!

Quick joke (with apologies beforehand to McGrath):-
What's the difference between an Essex girl and a refigerator?
A refigerator doesn't fart when you take your meat out.

More later!!!
