It's amazing how the same old-sayings can be found all over the country, just spoken a little differently. :)
My momma said this the other day and I had heard the first part before, but not the second:
"They don't have a pot to pee in or a window to throw it out of!"
I repeated it to the Old Hermit.
He's heard this version all his life:
"They ain't got a pot to p__s in or a winder to throw it out of!"
