1. The first Girl Scout cookies were sold in Muskogee, Oklahoma, in 1917, when troops baked cookies and sold them in high schools as a service project.
2. The ingredients for a Girl Scout cookie were very simple in 1922: Butter, sugar, eggs, milk, vanilla, flour, salt, and baking powder.
3. In 1933, you could get a box of 44 cookies for just 23 cents.
4. In the 1940s there were no Girl Scout cookies to be found. Due to shortages of sugar, butter, and flour, the Scouts sold calendars instead.
5. Today, one-quarter of all Girl Scout cookie sales are Thin Mints. There's just something about the chocolate and mint combination that is unbeatable (that, and the fact that Thin Mints have the most cookies in a box).
6. Two licensed bakeries are in charge of Girl Scout cookies: ABC Bakers and Little Brownie Bakers. That number has decreased dramatically over the years; in the 1940s there were 29 bakers, and in the 1960s, 14.
7. Depending on your local Girl Scout council (and which baker they purchased from), your cookies are either creatively named or literal: Tagalongs are also known as Peanut Butter Patties; Do-si-dos are Peanut Butter Sandwiches; and Trefoils are Shortbreads. Ever so slightly bucking the trend are Samoas/Caramel deLites.
