Shaving a cat

Don't you wonder where we get some of the expressions in the american language? For instance, who was the first dickhead that said, "a penny saved is a penny earned." Or, "a bird in the hand is worth two in the bush" or whatever. These sayings have inconvenienced me. Someone has said to me at one time or another, "Dont put all your eggs in one basket." I DONT HAVE EGGS, I DON'T HAVE A BASKET!! LEAVE ME ALONE ABOUT IT ALRIGHT! And it wasn't really my parents. My parents were cool like that. But someone, some time has said that to me. Makes me want to do something. Like, make a batch of cookies.
