At the far end of the scale:

It ain’t necessarily so
It ain’t necessarily so
De t’ings dat yo li’ble
To read in de Bible
It ain’t necessarily so
Methus’lah lived nine hundred years
Methus’lah lived nine hundred years
But who calls dat livin’
When no gal’ll give in
To no man what’s nine hundred years
I’m preachin’ dis sermon to show
It ain’t nessa, ain’t nessa
It ain’t necessarily so!

-- It Ain't Necessarily So; George & Ira Gershwin, from Porgy & Bess
