+\paragraph{{\Large\textmd{\textit{What is a Venn Diagram?}}}} And more importantly, why should I care?
+
+An excellent question! (Well, \textit{two} excellent questions, actually!)
+
+Venn diagrams were invented in the 1800s by an English mathematician named John Venn. ``Invented'' may be a strong word here, since Christian Weise and Leonhard Euler had proposed similar things previously (in 1712 and 1768, respectively). But John Venn is the person who gets the credit because he wrote about them in his 1881 book \textit{Symbolic Logic}. (Truthfully, he origially wrote about them in a paper titled ``On the Diagrammatic and Mechanical Representation of Propositions and Reasonings'' which was published in the \textit{Philosophical Magazine and Journal of Science} in 1880. (If you are interested, you can read it here: \kref{https://www.cis.upenn.edu/~bhusnur4/cit592_fall2014/venn\%20diagrams.pdf}{}{https://www.cis.upenn.edu/\~{}bhusnur4/cit59\_fall2014/venn\%diagrams.pdf}.)
+
+You probably don't care about any of that, though. 
+
+One of the best things you can do with Venn diagrams is to create humorous images to entertain both yourself and your friends. And if you can color them in, then you also have a coloring book, and that's even better!
+
+Yep, that's what you have — a coloring book of Venn diagrams. 
+
+So grab those coloring pencils, a mug of something warm and satisfying (or a glass of something cold and satisfying), and color to your heart's content.
