OK, FWIW, Monty Python didn't say that, at least not originally. They borrowed it from a WW II incident, and a song composed from it (The orchestral and choral arrangement is massive.).......
Here's one version (?) of the lyrics:
Down went the gunner, a bullet was his fate
Down went the gunner, and then the gunner’s mate
Up jumped the sky pilot, gave the boys a look
And manned the gun himself as he laid aside the Book, shouting
Praise the Lord and pass the ammunition
Praise the Lord and pass the ammunition
Praise the Lord and pass the ammunition
And we’ll all stay free
Praise the Lord and swing into position
Can’t afford to sit around a-wishin’
Praise the Lord, we’re all between perdition
And the deep blue sea
Yes the sky pilot said it
Ya gotta give him credit
For a son of a gun of a gunner was he, shouting
Praise the Lord, we’re on a mighty mission
All aboard, we’re not a-goin’ fishin’
Praise the Lord and pass the ammunition
And we’ll all stay free
Down came the bombers, a-diving from the sky
Down came the bombers, but faith could never die
There stood the sky pilot, there among his men
The light was in his eye, as he shouted once again
Praise the Lord and pass the ammunition
Praise the Lord and pass the ammunition
Praise the Lord and pass the ammunition
And we’ll all stay free
Praise the Lord and swing into position
>>Can’t afford to be a politician<<
Praise the Lord, we’re all between perdition
And the deep blue sea
Yes the sky pilot said it
Ya gotta give him credit
For a son of a gun of a gunner was he, shouting
Praise the Lord, we’re on a mighty mission
All aboard, we’re not a-goin’ fishin’
Praise the Lord and pass the ammunition
And we’ll all stay free
SO, If you haven't overdosed on this by now, here's the Wiki backstory:
