When I was visiting a Vicar in Mid Wales, a few years ago on business, he had a large parrot. It was in a bloody great huge cage, that was on pram wheels.
When I was trying to interview the Vicar, this parrot started screaming obscenities at me, in increasingly louder volumes. The obscenities were of such a level of disgusting-ness, that I am loath to even try to repeat them here.
I put up with this for a few minutes, but had to admit defeat. I asked the Vicar what on earth was going on ?
He explained that he had been a Royal Naval Chaplain for many years, and every time his back was turned, the ratings would teach the parrot a new swear word !
But, I argued, doesn't that produce some problems when the Mothers Union came around for tea, or when the conformation class is present ?
"That is why the **** has pram wheels on his cage, so I can whip him out into the garage when I have too", he replied !
