I asked my German friend to draw me an informational diagram. “Venn?" he asked. I replied, “As soon as you can.”

Happy Birthday John Venn!

(via @dgar@aus.social)

A humorous Venn diagram is shown, titled "In Honor of John Venn's 180th Birthday." It features two large circles: one green, labeled "People Who Are 180 Years Old," and one yellow, labeled "People Who Are Still Alive." These circles do not intersect. Below, a smaller Venn diagram shows three overlapping circles: blue for "People Who Understand Venn Diagrams," red for "People With a Sense of Humor," and the intersected area, purple, for "People Who Get This Joke." The credit "TechnicallyFunny.com" is at the bottom right.
