Back when the Internet was young and fertile. Before the time of Blogs. There were newsgroups. There still are newsgroups although they might not be as uplifting as they were back when.
The first "funny forward" email I ever received came from a friend of mine (who I believe was in Houston at the time). We'll call him Ed.
Ed sent me the Anal Fissure email. I don't know the exact authoring date of the story, but it seems like I first read it 15 or so years ago (in fact most postings seems to be dated 1993). It's still the funniest email I've ever received. I still giggle when I think about it.
Today, there are websites dedicated to the story of Bob. However, this is probably the best place to read it.
Just to whet your whistle, it starts out with, "After lurking about in the wings the required 2 months I have felt the need to tell you about my anal fissure Bob."
