This chart of mental diagnoses for the characters on Sesame Street has been making the rounds today, but it's not exactly new. It appeared about a year-and-a-half ago at Fo'Drizzle, but sometime after that lost its three watermarks and was passed around all over.
Even then, this is not the first attempt to diagnose all the mental problems of Sesame Street characters. Here's a post listing the Sesame Street character's various diagnoses from 2007. Another tried it in 2011. Even Psychology Today got into the act! You might notice that none of these lists agree with each other completely. The Muppet Show cast got the treatment, too. It's all speculation, of course, and highlights how we tend to label every kind of personality quirk as a mental disorder.
Elmo's diagnosis is spot-on.
