You don’t have to know how to read or write
When you’re out with a feller in the pale moonlight.
You don’t need to look in a book to find
What he thinks of the moon or what is on his mind.
That comes natcherly.

. . .

My uncle down in Texas
Cain’t even write his name.
He signs his checks with X-es
But they cash ’em jest the same!

— Irving Berlin, “Doin’ What Comes Natcherly” from Annie Get Your Gun
