The above joke from GUEST was an original of mine which was actually done in poetry and called "The power of prayer".....

Mrs Brown had a wayward parrot,
A pretty young thing called Flo.
Who was always swearing and talking,
In sexual innuendo.

Mrs Brown went for tea with the pastor,
One Sunday evening last year.
Where she saw his old parrot praying,
Which gave her a clever idea.

She asked the pastor at tea time,
Can I borrow your old parrot "Rex"
To try to influence my parrot Flo,
Who talks of nothing but sex.

She took Rex home the same evening,
He prayed all the way in the car.
She was really impressed by the old bird,
Whose manners outshone Flos by far.

But as soon as she put him in Flos cage,
She realised her greatest fears.
Flo said "Do you want some Rex" and Rex said,
"I've been praying for this for years"
