Mr. Bean looks all funny on the TV. However, if he were to be a real person, what sort of mental problem would he be suffering from?
There are a lot of similar questions on the internet:
Mr Bean suffers from selective mutism.
Rowan Atkinson created Mr Bean to satisfy his whim to create a physical comedy character that could be funny in all languages without the need for translation.
To achieve this, he decided to limit Mr Bean's dialogue in favour of amusing facial expressions, bodily actions and sounds.
As an educated guess, I don't think Mr Bean fits the criteria of Schizotypal Personality Disorder or Schzoid Personality Disorder. He may well be on the Autistic spectrum but presents as someone primarily living with Generalised Anxiety, which causes him to be quite avoidant and overcomplicate simple social dilemmas. Some people are simply rather unusual, but that doesn't automatically mean they must fit into one diagnostic criteria or another. ~ Been a Clinical Psychologist for five years, hope this helps!
