My DD has little patience with stupid people and I always said to her..."Don't expect too much from those to whom God gave so little".
I think I heard that from my Mother.
I like the stupid sayings too, like, I would ask my Dad where he was going and He'd say.."Down to Mike's below Jake's, where they make sweet Ginger cakes"..

When I was little I always wanted to go with him to get sweet ginger cakes...LOL!
