In 1924, Matilda Knucklebinder, while dancing the Charleston, added cocoa beans to her glass of milk, simultaneously creating both chocolate milk and the modern milk shake. When recently asked about it, the 99 year old blew off the idea she was creating a international treat, and was really trying to attract a heavy boy across the room saying, and I quote, "My milk shake brings all the boys to the yard, and they're like, it's better than yours, damn right it's better than yours, I can teach you, but I have to charge".
