The Comic Venn Diagram. An Internet meme I don't love as much as I should.
You've seen the allegedly funny Venn diagrams. Other than cats, Lady Gaga, porn and allegedly funny Venn diagrams, I don't know what people use the Internets for. As a mathematician, these should be right up my alley, but most don't quite step up to the mark.
This one, on the other hand, made me smile, so I share it here, part of that whole "viral" concept.
