Mathemachicken Funny Math Chicken

Are you a mathematician who likes farm animals, specifically chickens? So there's this chicken who can do math like an animal! Here's a vintage picture of her, and the mathematics and chicken scratchings of equations she's doing in her head are in the thought bubble on top. Below is an old fashioned looking ribbon label that says "Mathemachicken," making this look like a kind of weird flyer for a circus act. But it's only a math pun in a math joke, the kind a funny math teacher might tell in class.
