Anyhoo, What is an evil twin and how do you spot them? Well, here's yours truly laying down the truth on twins of the evil variety.
Where is my head? I did leave out one important way to recognize an evil twin: Evil British accent. Other accents are, of course, possible, but an evil British one is always a dead give away.
Now, it's very important that you keep up on all current information concerning the identification of evil twins. Here's a little article you should read called "How to Spot Your Evil Twin". If you like that, you should rush out and by this little booky: Everything Explained Through Flowcharts by Doogie Horner. The book explains everything, including the Klingon Afterlife--no kidding.
