Apparently today is National Cleavage Day! How have I not heard of this before? It’s probably a guy’s response to Sweetest Day. And why isn’t National Cleavage Day during the summer? There’s no one really out “celebrating” on this cold March day. Anyways, in honor of this new found holiday, here are some photos of the greatest cleavage the world has ever known…Jayne Mansfield.

During the 50s and 60s, Jayne took a back seat to another blonde bombshell, a certain girl named Marilyn. She did have a real talent for acting though. She just couldn’t “bust out” of the dumb blonde roles that she was cast into. It was even known that Jayne had an IQ of 163! But boy, those boobs. So today on National Cleavage Day, I say we celebrate only one woman, the glorious pre-boob job era, Jayne Mansfield. To quote Jerry Seinfeld, “You know that Jayne Mansfield, she had some big breasts.”
